Protein Information (annotations from UniProt)

Database IDHIV0008383
UniProt IDO14543
Primary gene name(s)SOCS3
Synonym gene name(s)CIS3, SSI3
Protein nameSuppressor of cytokine signaling 3
Protein functionSOCS family proteins form part of a classical negative feedback system that regulates cytokine signal transduction. SOCS3 is involved in negative regulation of cytokines that signal through the JAK/STAT pathway. Inhibits cytokine signal transduction by binding to tyrosine kinase receptors including gp130, LIF, erythropoietin, insulin, IL12, GCSF and leptin receptors. Binding to JAK2 inhibits its kinase activity. Suppresses fetal liver erythropoiesis. Regulates onset and maintenance of allergic responses mediated by T-helper type 2 cells. Regulates IL-6 signaling in vivo, By similarity. Probable substrate recognition component of a SCF-like ECS, Elongin BC-CUL2/5-SOCS-box protein E3 ubiquitin-protein ligase complex which mediates the ubiquitination and subsequent proteasomal degradation of target proteins. Seems to recognize IL6ST, By similarity. {ECO:0000250, ECO:0000269|PubMed:15601820}.
