Background: Nicotinamide mononucleotide adenylyl transferases (NMNATs) catalyze the reversible reaction of ATP with NaMN (nicotinic acid mononucleotide) or NMN (nicotinamide mononucleotide) to produce NaAD (nicotinic acid adenine dinucleotide) or NAD (nicotinamide adenine dinucleotide). NAD is an essential cofactor or substrates for many enzymes like PARP1 and Sirt1 that regulate diverse cellular processes including oxidative reactions and transcription. NMNATs maintain NAD levels for internal homeostasis (1,2). NMNAT1 is localized to the nucleus and loss-of-function mutant in mice causes embryonic lethality (3). In humans, several different NMNAT1 mutations are associated with Leber congenital amaurosis (LCA), the most common cause of inherited childhood blindness (4-7).

Background: Nitric Oxide Synthase (NOS) catalyzes the formation of nitric oxide (NO) and citruline from L-arginine, oxygen and cofactors. Three family members have been characterized: neuronal NOS (nNOS), which is found primarily in neuronal tissue; inducible NOS (iNOS), which is induced by interferon gamma and lipopolysaccharides in the kidney and cardiovascular system; and endothelial NOS (eNOS), which is expressed in blood vessels (1). NO is a messenger molecule with diverse functions throughout the body including the maintenance of vascular integrity, homeostasis, synaptic plasticity, long-term potentiation, learning, and memory (2,3).

Background: Nucleolor protein 66 (NO66), also known as Myc-associated protein with a jumonji C (JmjC) domain (MAPJD), or ribosomal oxygenase 1, belongs to a large family of JmjC-domain-containing oxygenase proteins. NO66 exhibits both ribosomal histidine hydroxylase and histone demethylase activities, and plays a key role in regulation of gene transcription, RNA processing, and translation. NO66-mediated hydroxylation of ribosomal protein L8 (Rpl8) may play a role in regulation of protein synthesis (1). NO66 also functions to repress transcription by demethylating histone H3 lys4 and lys36, two histone marks that are important for transcriptional activation (2). The interaction of NO66 with the transcription factor osterix (OSX) regulates osteoblast differentiation and bone formation through repression of OSX target genes (3,4). In embryonic stem cells, the PHF19 protein recruits NO66 along with polycomb repressor complex 2 (PRC2) to differentiation-specific target genes to repress transcription through demethylation of histone H3 lys36 and methylation of histone H3 lys27, the latter mark being associated with transcriptional repression (2). NO66 is overexpressed in non-small cell lung cancer and colorectal cancer, and is associated with poor prognosis (5,6).

Background: YAP (Yes-associated protein, YAP65) was identified based on its ability to associate with the SH3 domain of Yes. It also binds to other SH3 domain-containing proteins such as Nck, Crk, Src, and Abl (1). In addition to the SH3 binding motif, YAP contains a PDZ interaction motif, a coiled-coil domain, and WW domains (2-4). While initial studies of YAP all pointed towards a role in anchoring and targeting to specific subcellular compartments, subsequent studies showed that YAP is a transcriptional co-activator by virtue of its WW domain interacting with the PY motif (PPxY) of the transcription factor PEBP2 and other transcription factors (5). In its capacity as a transcriptional co-activator, YAP is now widely recognized as a central mediator of the Hippo Pathway, which plays a fundamental and widely conserved role in regulating tissue growth and organ size. Phosphorylation at multiple sites (e.g., Ser109, Ser127) by LATS kinases promotes YAP translocation from the nucleus to the cytoplasm, where it is sequestered through association with 14-3-3 proteins (6-8). These LATS-driven phosphorylation events serve to prime YAP for subsequent phosphorylation by CK1δ/ε in an adjacent phosphodegron, triggering proteosomal degradation of YAP (9).

Background: β-Catenin is a key downstream effector in the Wnt signaling pathway (1). It is implicated in two major biological processes in vertebrates: early embryonic development (2) and tumorigenesis (3). CK1 phosphorylates β-catenin at Ser45. This phosphorylation event primes β-catenin for subsequent phosphorylation by GSK-3β (4-6). GSK-3β destabilizes β-catenin by phosphorylating it at Ser33, Ser37, and Thr41 (7). Mutations at these sites result in the stabilization of β-catenin protein levels and have been found in many tumor cell lines (8).

Background: PTEN (phosphatase and tensin homologue deleted on chromosome ten), also referred to as MMAC (mutated in multiple advanced cancers) phosphatase, is a tumor suppressor implicated in a wide variety of human cancers (1). PTEN encodes a 403 amino acid polypeptide originally described as a dual-specificity protein phosphatase (2). The main substrates of PTEN are inositol phospholipids generated by the activation of the phosphoinositide 3-kinase (PI3K) (3). PTEN is a major negative regulator of the PI3K/Akt signaling pathway (1,4,5). PTEN possesses a carboxy-terminal, noncatalytic regulatory domain with three phosphorylation sites (Ser380, Thr382, and Thr383) that regulate PTEN stability and may affect its biological activity (6,7). PTEN regulates p53 protein levels and activity (8) and is involved in G protein-coupled signaling during chemotaxis (9,10).

Background: Translation repressor protein 4E-BP1 (also known as PHAS-1) inhibits cap-dependent translation by binding to the translation initiation factor eIF4E. Hyperphosphorylation of 4E-BP1 disrupts this interaction and results in activation of cap-dependent translation (1). Both the PI3 kinase/Akt pathway and FRAP/mTOR kinase regulate 4E-BP1 activity (2,3). Multiple 4E-BP1 residues are phosphorylated in vivo (4). While phosphorylation by FRAP/mTOR at Thr37 and Thr46 does not prevent the binding of 4E-BP1 to eIF4E, it is thought to prime 4E-BP1 for subsequent phosphorylation at Ser65 and Thr70 (5).

Background: The Src family of protein tyrosine kinases, which includes Src, Lyn, Fyn, Yes, Lck, Blk, and Hck, are important in the regulation of growth and differentiation of eukaryotic cells (1). Src activity is regulated by tyrosine phosphorylation at two sites, but with opposing effects. While phosphorylation at Tyr416 in the activation loop of the kinase domain upregulates enzyme activity, phosphorylation at Tyr527 in the carboxy-terminal tail by Csk renders the enzyme less active (2).

Background: Striatal enriched phosphatase (STEP, also known as PTPN5), is a protein tyrosine phosphatase expressed in dopaminoceptive neurons of the central nervous system (1). Alternative splicing produces the cytosolic STEP46 and the membrane-associated STEP61 isoforms of STEP. Dopamine activates D1 receptors and PKA, which in turn phosphorylate both isoforms of STEP. Phosphorylation of STEP61 occurs at Ser160 and Ser221, while STEP46 is phosphorylated at Ser49 (equivalent to Ser221 of STEP61) (2). NMDA-mediated activation of STEP is an important mechanism for regulation of Erk activity in neurons (3). Furthermore, STEP is involved in the regulation of both NMDAR and AMPAR trafficking (4,5). Due to its importance in cognitive function, STEP may play a role in Alzheimer's disease (1).

Background: Notch proteins (Notch1-4) are a family of transmembrane receptors that play important roles in development and the determination of cell fate (1). Mature Notch receptors are processed and assembled as heterodimeric proteins, with each dimer comprised of a large extracellular ligand-binding domain, a single-pass transmembrane domain, and a smaller cytoplasmic subunit (Notch intracellular domain, NICD) (2). Binding of Notch receptors to ligands of the Delta-Serrate-Lag2 (DSL) family triggers heterodimer dissociation, exposing the receptors to proteolytic cleavages; these result in release of the NICD, which translocates to the nucleus and activates transcription of downstream target genes (3,4).

Background: Phorbol-12-myristate-13-acetate-induced protein 1 (PMAIP1, Noxa) is a small protein that plays a key role in mediating apoptotic signaling. Noxa is a pro-apoptotic Bcl-2 family protein that contains a single Bcl-2 homology (BH3) domain (1). Members of the “BH3-only” family (e.g. Noxa, Bad, Bim, Puma, Bid, Bik, and Hrk) are highly regulated proteins that induce apoptosis through BH3-dependent interaction with anti-apoptotic Bcl-2 family proteins (2). Noxa localizes to mitochondria and binds the anti-apoptotic proteins Mcl-1 and A1/Bfl-1, but does not bind to Bcl-2 or Bcl-xL (3). The Noxa protein competes with Mcl-1 for binding to mitochondrial Bak protein. Noxa was originally identified as a phorbol ester inducible protein that is highly expressed in adult T-cell leukemia cell lines (4). Several different stimuli, including DNA damage, hypoxia, interferon, viral infection, and double-stranded RNA, induce Noxa expression in cells. Higher levels of Noxa protein are typically found hematopoietic cells (3,5,6).

Background: The mTORC1 kinase complex plays a critical role in cell growth regulation (1, 2). mTORC1 activity is modulated by cellular and environmental factors (e.g., energy levels, growth factors, and amino acids) (3, 4). Amino acid sensing is mediated through several protein complexes, including GATOR (GAP Activity TOward Rags). GATOR is composed of two protein subcomplexes (GATOR1 and GATOR2) that function in opposing fashion to regulate mTORC1 activity. NPRL2 was identified as a component of the GATOR1 subcomplex (also containing DEPDC5 and NPRL3) that functions to negatively regulate mTORC1 activity through activation of RagA and RagB GTPases (5). Conversely, the GATOR2 subcomplex (containing Mios, WDR24, WDR59, Seh1L, and Sec13) positively regulates mTORC1 activity (5). In addition, NPRL2, also known as TUSC4 (tumor suppressor candidate 4), has been shown to prevent the degradation of tumor suppressor BRCA1. Overexpression of TUSC4 (NPRL2) protein inhibits proliferation of breast cancer cells (6).

Background: NAD(P)H:quinone oxidoreductase 1 (NQO1) is a flavoprotein that catalyzes the two-electron reduction of quinones and their derivatives (1,2). This enzyme protects cells against redox cycling and oxidative stress (1,3). The expression of NQO1 is increased in liver, colon and breast tumors and non-small cell lung cancer (NSCLC) compared with the normal tissues (1,2). Moreover, expression levels are also elevated in developing tumors, suggesting a role for NQO1 in the prevention of tumor development (1). Studies on NQO1 knockout mice suggest that the lack of NQO1 enzymatic activity changes intracellular redox states resulting in a reduction in apoptosis, which in turn leads to myeloid hyperplasia of bone marrow (2).

Background: Nuclear Receptor Binding Factor-2 (NRBF-2), also referred to as Comodulator of PPAR and RXRα-2 (COPR-2), has been shown to interact with the AF-2 region of several nuclear hormone receptors with varying affinities such as PPARα, RARα, RARγ, and RXRα (1,2). NRBF-2 contains a LLYLL motif, which matches the LXXLL NR box consensus and is required for functional NRBF-2/nuclear receptor complex formation and repression of receptor function. NRBF-2 also contains a unique autonomous activation domain and, thus, does not completely abrogate nuclear receptor function, suggesting that NRBF-2 might serve as a molecular rheostat to fine-tune the transcriptional activity of liganded nuclear receptors (1,2).
