Methylation of cytosines located 5' to guanosine is known to have a profound effect on the expression of several eukaryotic genes (Bird, 1992). In normal cells, methylation occurs predominantly in CG-poor regions, while CG-rich areas, called CpG islands, remain unmethylated. Aberrant methylation of normally unmethylated CpG islands has been documented as a relatively frequent event in immortalized and transformed cells (Antequera, 1990) and has been associated with transcriptional inactivation of defined tumor suppressor genes in human cancers (Herman, 1994; Merlo, 1995). The suppressor of cytokine signaling-1 (SOCS1) gene exhibits characteristic hypermethylation.
Methylation-specific PCR (MSP) is a new technology for sensitive detection of abnormal gene methylation utilizing small amounts of DNA (Herman, 1996). This process employs an initial bisulfite reaction to modify the DNA, followed by PCR amplification with specific primers designed to distinguish methylated from unmethylated DNA.

Application Notes
Principles of the Technique Use of either the CpGenome™ DNA Modification Kit (Cat. No. S7820) or the CpGENOME™ Fast DNA Modification Kit (Cat. No. S7824) facilitates the initial bisulfite reactions, while the CpG WIZ® SOCS1 Amplification Kit contains the reagents required for the gene-specific PCR amplification reactions.
This gene encodes a member of the STAT-induced STAT inhibitor (SSI), also known as suppressor of cytokine signaling (SOCS), family. SSI family members are cytokine-inducible negative regulators of cytokine signaling. The expression of this gene can be induced by a subset of cytokines, including IL2, IL3 erythropoietin (EPO), CSF2/GM-CSF, and interferon (IFN)-gamma. The protein encoded by this gene functions downstream of cytokine receptors, and takes part in a negative feedback loop to attenuate cytokine signaling. Knockout studies in mice suggested the role of this gene as a modulator of IFN-gamma action, which is required for normal postnatal growth and survival.
FUNCTION: SwissProt: O15524 # SOCS family proteins form part of a classical negative feedback system that regulates cytokine signal transduction. SOCS1 is involved in negative regulation of cytokines that signal through the JAK/STAT3 pathway. Through binding to JAKs, inhibits their kinase activity. In vitro, also suppresses Tec protein- tyrosine activity. Appears to be a major regulator of signaling by interleukin 6 (IL6) and leukemia inhibitory factor (LIF). Regulates interferon-gamma mediated sensory neuron survival (By similarity). Probable substrate-recognition component of a SCF- like ECS (Elongin-Cullin-SOCS-box protein) E3 ubiquitin ligase complex which mediates the ubiquitination and subsequent proteasomal degradation of target proteins. Seems to recognize JAK2. SIZE: 211 amino acids; 23551 Da SUBUNIT: Interacts with multiple activated signaling proteins of the tyrosine kinase signaling pathway including JAK family kinases, TEC, KIT, GRB2 and VAV. Binding to JAKs is mediated through the KIR and SH2 domains to a phosphorylated tyrosine residue within the JAK JH1 domain. Binds the SH3 domain of GRB2 via diproline determinants in the N-terminus, and the N-terminal regulatory domain of VAV (By similarity). Interacts with the Elongin BC complex (TCEB1 and TCEB2). Component of an ECS CBC(VHL) E3 ubiquitin ligase complex which contains Elongin BC complex, CUL5, RBX1 and SOCS1 (By similarity). Interacts with TRIM8 (By similarity). Interacts with CUL2. TISSUE SPECIFICITY: Expressed in all tissues with high expression in spleen, small intestine and peripheral blood leukocytes. DOMAIN: SwissProt: O15524 The ESS and SH2 domains are required for JAK phosphotyrosine binding. Further interaction with the KIR domain is necessary for signal and kinase inhibition. & The SOCS box domain mediates the interaction with the Elongin BC complex, an adapter module in different E3 ubiquitin ligase complexes. The Elongin BC complex binding domain is also known as BC-box with the consensus [APST]-L-x(3)-C-x(3)-[AILV] and is part of the SOCS box (By similarity). SIMILARITY: Contains 1 SH2 domain. & Contains 1 SOCS box domain.
