Background: The suppressor of cytokine signaling (SOCS) family members are negative regulators of cytokine signal transduction that inhibit the Jak/Stat pathway (1-3). The SOCS family consists of at least 8 members including the originally identified cytokine-inducible SH2-containing protein (CIS1), as well as SOCS1-7. Each SOCS family member contains a central SH2 domain and a conserved carboxy-terminal motif designated as the SOCS box. These proteins are important regulators of cytokine signaling, proliferation, differentiation, and immune responses.

Background: Members of the Janus family of tyrosine kinases (Jak1, Jak2, Jak3, and Tyk2) are activated by ligands binding to a number of associated cytokine receptors (1). Upon cytokine receptor activation, Jak proteins become autophosphorylated and phosphorylate their associated receptors to provide multiple binding sites for signaling proteins. These associated signaling proteins, such as Stats (2), Shc (3), insulin receptor substrates (4), and focal adhesion kinase (FAK) (5), typically contain SH2 or other phospho-tyrosine-binding domains.

Background: Tyk2 is a member of the Jak family of protein tyrosine kinases. It associates with and is activated by receptors for many cytokines including IL-13, the IL-6 family, IL-10, and IFN-α and β (1-3). Following ligand binding, Tyk2 is activated by phosphorylation of Tyr1054 and/or Tyr1055 (4). Tyk2 is required for the tyrosine phosphorylation of Stat3 in the IFN-β signaling cascade (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: The maintenance of glucose homeostasis is an essential physiological process that is regulated by hormones. An elevation in blood glucose levels during feeding stimulates insulin release from pancreatic β cells through a glucose sensing pathway (1). Insulin is synthesized as a precursor molecule, proinsulin, which is processed prior to secretion. A- and B-peptides are joined together by a disulfide bond to form insulin, while the central portion of the precursor molecule is cleaved and released as the C-peptide. Insulin stimulates glucose uptake from blood into skeletal muscle and adipose tissue. Insulin deficiency leads to type 1 diabetes mellitus (2).

Background: Ack1 and Ack2 (activated cdc42-associated kinase 1 and 2) are non-receptor tyrosine kinases that consist of a tyrosine kinase core, an SH3 domain, a cdc42/Rac-binding (CRIB) domain, a Ralt homology region and a proline-rich region (1,2). Ack1 and 2 are the only two tyrosine kinases known to interact with cdc42. Both Acks are activated by growth factors including EGF and PDGF, as well as by activated integrins through cell adhesion, and may serve to link receptor tyrosine kinase or G protein-coupled receptor signaling with cdc42. Acks may regulate cell growth, morphology and motility (3,4). Recent findings indicate that Ack1 may play a role in prostate tumorigenesis, making it a potential drug target for this type of cancer (5).

Background: Glucose homeostasis is regulated by hormones. Elevation of blood glucose levels during feeding stimulates insulin release from pancreatic β-cells through a glucose sensing pathway (1). Proinsulin, the insulin precursor molecule, is processed prior to its secretion. Insulin is composed of A-peptide and B-peptide which are joined by a disulfide bond. The center one-third of the molecule is cleaved and released as C-peptide, which has a longer half-life than insulin (2).

Background: Angiotensinogen (AGT) is the primary precursor of angiotensins, peptide hormones that play a central role in the renin-angiotensin system (RAS) (1-3). AGT is a secreted protein synthesized primarily by the liver and secreted into circulation. Upon binding to renin, the amino terminal fragment of AGT is cleaved and released as a decapeptide hormone termed angiotensin 1 (Ang I). Ang I is subsequently processed by angiotensin converting enzyme (ACE) to generate angiotensin II (Ang II), which acts on AT1 and AT2 receptors in the central nervous system to increase production of anti-diuretic hormone (ADH), while promoting vasoconstriction in the peripheral circulation (4). Aberrant upregulation of Ang II has been associated with numerous clinical conditions, including hypertension, atherosclerosis, myocardial hypertrophy, and obesity (5-7). Alternative cleavage products of Ang I (e.g., Ang 1-7) can also be generated by ACE2 cleavage, some of which display biological functions that are distinct from Ang II (8). Treatments that target the RAS (e.g., ACE inhibitors) are consequently of significant importance in the treatment of hypertensive and hypertensive-related disorders(5-8).

Background: The type II receptor for Müllerian inhibiting substance (MIS), also known as the anti-Müllerian hormone receptor 2 (AMHR2), binds a hormone-ligand that directs the incomplete development of Müllerian ducts in male embryos (1,2). MIS-R2 is a single transmembrane serine/threonine kinase receptor of the TGF-β receptor family involved in the phosphorylation of shared type 1 receptors and Smad transcriptional regulators (3,4). MIS produced by the fetal testis promotes the regression of Müllerian ducts that would otherwise differentiate into the uterus and fallopian tubes in the male fetus (5). Corresponding MIS-R2 gene mutations can cause persistent Müllerian duct syndrome type 2 (PMDS-2), a form of male pseudohermaphroditism characterized by a failure of Müllerian duct regression (6). The presence of MIS-R2 is observed in ovarian cancer cell lines that respond positively to treatment with recombinant MIS, suggesting that both receptor and ligand may be important therapeutic tools (7).
