[https://www.uniprot.org/uniprot/SOCS3_MOUSE SOCS3_MOUSE] SOCS 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. 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 (By similarity). Seems to recognize IL6ST.<ref>PMID:9889194</ref> <ref>PMID:10821852</ref> <ref>PMID:10490101</ref> <ref>PMID:12754505</ref> <ref>PMID:12847520</ref>

== Publication Abstract from PubMed ==
SOCS3 is essential for regulating the extent, duration, and specificity of cellular responses to cytokines such as G-CSF and IL-6. Here we describe the solution structure of SOCS3, the first structure determined for any SOCS protein, in complex with a phosphotyrosine-containing peptide from the IL-6 receptor signaling subunit gp130. The structure of the complex shows that seven peptide residues form a predominantly hydrophobic binding motif. Regions outside the SOCS3 SH2 domain are important for ligand binding, in particular, a single 15 residue alpha helix immediately N-terminal to the SH2 domain makes direct contacts with the phosphotyrosine binding loop and, in part, determines its geometry. The SH2 domain itself is remarkable in that it contains a 35 residue unstructured PEST motif insertion that is not required for STAT inhibition. The PEST motif increases SOCS3 turnover and affects its degradation pathway, implying that it has an important regulatory role inside the cell.
