  • FunctionSOCS 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 an ECS (Elongin BC-CUL2/5-SOCS-box protein) E3 ubiquitin ligase complex which mediates the ubiquitination and subsequent proteasomal degradation of target proteins. Seems to recognize JAK2.
  • Tissue specificityExpressed in all tissues with high expression in spleen, small intestine and peripheral blood leukocytes.
  • PathwayProtein modification; protein ubiquitination.
  • Sequence similaritiesContains 1 SH2 domain.
    Contains 1 SOCS box domain.
  • DomainThe 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.

Thank you for your enquiry. The differences between goat polyclonal to SOCS1 (ab9870) and rabbit polyclonal to SOCS1 (ab3691) is that ab9870 reacts with mouse and is predicted to react with human due to sequence homology. So far it has only been sh...
