CPGWIZ^™ SOCS1 - Methylation specific PCR assay

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.

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 TM=["CPGWIZ"] SOCS1 Amplification Kit contains the reagents required for the gene-specific PCR amplification reactions.

The components of the CPG WIZ SOCS1 Amplification Kit include those required for PCR amplification after bisulfite modification of DNA samples. Sufficient reagents are provided to analyze 25 samples with appropriate controls.
