Background: Nectin-2, also known as CD112 and poliovirus receptor-related 2 (PVRL2), is a single-pass type I membrane glycoprotein ubiquitously expressed on various human tissues (1). It is a calcium independent cell adhesion molecule known to interact with several cell surface receptors, including DNAM-1 (CD226), LFA-1 (CD11a), Nectin-3 (CD113), TIGIT (VSTM3), and PVRIG (CD112R) (2-7). It is one of the major constituents of adherins junctions, and therefore plays a central role in a number of cellular processes, including adhesion, migration, and proliferation (2-8). Within the immune system, Nectin-2 modulates immune cell signaling. Upon interaction with DNAM-1 expressed on T and NK cells, Nectin-2 stimulates proliferation and cytokine production (4). Upon interaction with PVRIG, Nectin-2 inhibits proliferation (7). Thus, Nectin-2 can be either a co-stimulator or a co-inhibitor of immune cell function depending on competitive receptor interactions. Nectin-2 also serves as an entry for certain mutant strains of herpes simplex virus and pseudorabies virus, and it is involved in cell to cell spreading of these viruses (8,9). Alternate transcriptional splice variants, encoding different isoforms, have been characterized (10,11).

Background: The Drosophila piwi gene was identified as being required for the self-renewal of germline stem cells (1). Piwi homologs are well conserved among various species including Arabidopsis, C. elegans, and Homo sapiens (1). Both Miwi and Mili proteins are mouse homologs of Piwi and contain a C-terminal Piwi domain (2). Miwi and Mili bind to Piwi-interacting RNAs (piRNAs) in male germ cells and are essential for spermatogenesis in mice (3-5).

Background: LKB1 (STK11) is a serine/threonine kinase and tumor suppressor that helps control cell structure, apoptosis and energy homeostasis through regulation of numerous downstream kinases (1,2). A cytosolic protein complex comprised of LKB1, putative kinase STRAD, and the MO25 scaffold protein, activates both AMP-activated protein kinase (AMPK) and several AMPK-related kinases (3). AMPK plays a predominant role as the master regulator of cellular energy homeostasis, controlling downstream effectors that regulate cell growth and apoptosis in response to cellular ATP concentrations (4). LKB1 appears to be phosphorylated in cells at several sites, including human LKB1 at Ser31/325/428 and Thr189/336/363 (5).Mutation in the corresponding LKB1 gene causes Peutz-Jeghers syndrome (PJS), an autosomal dominant disorder characterized by benign GI tract polyps and dark skin lesions of the mouth, hands, and feet (6). A variety of other LKB1 gene mutations have been associated with the formation of sporadic cancers in several tissues (7).

Background: c-Kit is a member of the subfamily of receptor tyrosine kinases that includes PDGF, CSF-1, and FLT3/flk-2 receptors (1,2). It plays a critical role in activation and growth in a number of cell types including hematopoietic stem cells, mast cells, melanocytes, and germ cells (3). Upon binding with its stem cell factor (SCF) ligand, c-Kit undergoes dimerization/oligomerization and autophosphorylation. Activation of c-Kit results in the recruitment and tyrosine phosphorylation of downstream SH2-containing signaling components including PLCγ, the p85 subunit of PI3 kinase, SHP2, and CrkL (4). Molecular lesions that impair the kinase activity of c-Kit are associated with a variety of developmental disorders (5), and mutations that constitutively activate c-Kit can lead to pathogenesis of mastocytosis and gastrointestinal stromal tumors (6). Tyr719 is located in the kinase insert region of the catalytic domain. c-Kit phosphorylated at Tyr719 binds to the p85 subunit of PI3 kinase in vitro and in vivo (7).

Background: The modulation of chromatin structure is an essential component in the regulation of transcriptional activation and repression. Modifications can be made by at least two evolutionarily conserved strategies, through the disruption of histone-DNA contacts by ATP-dependent chromatin remodelers, or by histone tail modifications including methylation and acetylation. One of the four classes of ATP-dependent histone remodelers is the SWI/SNF complex, the central catalytic subunit of which is Brg1 or the highly related protein hBRM (1). This SWI/SNF complex contains varying subunits but its association with either Brg1 or hBRM remains constant (1). SWI/SNF complexes have been shown to regulate gene activation, cell growth, the cell cycle and differentiation (1). Brg1/hBRM have been shown to regulate transcription through enhancing transcriptional activation of glucocorticoid receptors (2). Although usually associated with transcriptional activation, Brg1/hBRM have also been found in complexes associated with transcriptional repression including with HDACs, Rb and Tif1β (3-5). Brg1/hBRM plays a vital role in the regulation of gene transcription during early mammalian embryogenesis. In addition, Brg1/hBRM also play a role as a tumor suppressors and Brg1 is mutated in several tumor cell lines (6-8).

Application Methods: Chromatin IP, Immunofluorescence (Immunocytochemistry), Immunohistochemistry (Paraffin), Immunoprecipitation, Western Blotting

Background: ATP-dependent chromatin remodeling complexes play an essential role in the regulation of various nuclear processes, such as gene expression, DNA replication, and repair (1,2). The SWI/SNF chromatin remodeling complex consists of more than 10 subunits with a single molecule of the ATPase catalytic subunit BRM or BRG1, but not both. The activities of these two subunits drive the disruption of histone-DNA contacts that lead to changes in accessibility of crucial regulatory elements within chromatin (2-5). The BRM/BRG1 containing SWI/SNF complexes are recruited to target promoters by transcription factors, such as nuclear receptors, p53, RB, and BRCA1 to regulate gene activation, cell growth, the cell cycle, and differentiation processes (1,6-9). BRM and BRG1 are also considered to be tumor suppressors and their expression levels are severely reduced in several cancer cell lines (10-13).

Background: Quaking (QKI) is a member of the signal transduction and activator of RNA (STAR) protein family of RNA binding proteins (1,2). Mutations in the mouse Qki locus results in impaired myelin formation resulting in tremors (3). QKI proteins exist as homodimers, and disruption of the dimerization process is lethal in mice (2). QKI exists in different isoforms that differ in their C-terminus, resulting in unique subcellular localizations (4). The nuclear isoform of QKI, QKI-5, is involved in regulation of alternative splicing of MAG mRNA, which encodes for a protein important for myelin sheath formation and maintenance (4,5). QKI has also been implicated in schizophrenia and oligodendrocyte differentiation (6). QKI can function as a tumor suppressor, as it is regulated by p53 to stabilize miRNAs that regulate TGF-Β signaling (7).
