CC   -!- FUNCTION: SOCS family proteins form part of a classical negative
CC       feedback system that regulates cytokine signal transduction. SOCS3 is
CC       involved in negative regulation of cytokines that signal through the
CC       JAK/STAT pathway. Inhibits cytokine signal transduction by binding to
CC       tyrosine kinase receptors including IL6ST/gp130, LIF, erythropoietin,
CC       insulin, IL12, GCSF and leptin receptors. Binding to JAK2 inhibits its
CC       kinase activity and regulates IL6 signaling. Suppresses fetal liver
CC       erythropoiesis. Regulates onset and maintenance of allergic responses
CC       mediated by T-helper type 2 cells (By similarity). Probable substrate
CC       recognition component of a SCF-like ECS (Elongin BC-CUL2/5-SOCS-box
CC       protein) E3 ubiquitin-protein ligase complex which mediates the
CC       ubiquitination and subsequent proteasomal degradation of target
CC       proteins (PubMed:15601820). {ECO:0000250|UniProtKB:O35718,
CC       ECO:0000269|PubMed:15601820}.
CC   -!- PATHWAY: Protein modification; protein ubiquitination.
CC   -!- SUBUNIT: Interacts with multiple activated proteins of the tyrosine
CC       kinase signaling pathway including IGF1 receptor, insulin receptor and
CC       JAK2. Binding to JAK2 is mediated through the KIR and SH2 domains to a
CC       phosphorylated tyrosine residue within the JAK2 JH1 domain
CC       (PubMed:10421843). Binds specific activated tyrosine residues of the
CC       leptin, EPO, IL12, GSCF and gp130 receptors (PubMed:12027890,
CC       PubMed:14559241). Interaction with CSNK1E stabilizes SOCS3 protein
CC       (PubMed:15070676). Component of the probable ECS(SOCS3) E3 ubiquitin-
CC       protein ligase complex which contains CUL5, RNF7/RBX2, Elongin BC
CC       complex and SOCS3 (PubMed:15601820). Interacts with CUL5, RNF7, ELOB
CC       and ELOC (PubMed:15601820). Interacts with CUL2 (PubMed:15601820).
CC       Interacts with FGFR3 (PubMed:16410555). Interacts with INSR (By
CC       similarity). Interacts with BCL10; this interaction may interfere with
CC       BCL10-binding with PELI2 (By similarity). Interacts with NOD2 (via CARD
CC       domain); the interaction promotes NOD2 degradation (PubMed:23019338).

CC   -!- TISSUE SPECIFICITY: Widely expressed with high expression in heart,
CC       placenta, skeletal muscle, peripheral blood leukocytes, fetal and adult
CC       lung, and fetal liver and kidney. Lower levels in thymus.
CC   -!- DOMAIN: The ESS and SH2 domains are required for JAK phosphotyrosine
CC       binding. Further interaction with the KIR domain is necessary for
CC       signal and kinase inhibition.
CC   -!- DOMAIN: The SOCS box domain mediates the interaction with the Elongin
CC       BC complex, an adapter module in different E3 ubiquitin ligase
CC       complexes. {ECO:0000250}.
CC   -!- PTM: Phosphorylated on tyrosine residues after stimulation by the
CC       cytokines, IL-2, EPO or IGF1.
CC   -!- DISEASE: Note=There is some evidence that SOCS3 may be a susceptibility
CC       gene for atopic dermatitis linked to 17q25. SOCS3 messenger RNA is
CC       significantly more highly expressed in skin from patients with atopic
CC       dermatitis than in skin from healthy controls. Furthermore, a genetic
CC       association between atopic dermatitis and a haplotype in the SOCS3 gene
CC       has been found in two independent groups of patients.
