This gene encodes a member of the STAT-induced STAT inhibitor (SSI), also known as suppressor of cytokine signaling (SOCS), family. SSI family members are cytokine-inducible negative regulators of cytokine signaling. The expression of this gene can be induced by a subset of cytokines, including IL2, IL3 erythropoietin (EPO), CSF2/GM-CSF, and interferon (IFN)-gamma. The protein encoded by this gene functions downstream of cytokine receptors, and takes part in a negative feedback loop to attenuate cytokine signaling. Knockout studies in mice suggested the role of this gene as a modulator of IFN-gamma action, which is required for normal postnatal growth and survival.,SOCS1,CIS1,CISH1,JAB,SOCS-1,SSI-1,SSI1,TIP3,TIP-3,Epigenetics & Nuclear Signaling,Signal Transduction,Cell Biology & Developmental Biology,Ubiquitin,Ubiquitin-Proteasome Signaling Pathway,Immunology & Inflammation,IL-6 Receptor Signaling Pathway,Toll-like Receptor Signaling Pathway,SOCS1
