Suppressor of cytokine signaling 3 (SOCS3 or SOCS-3) is a protein that in humans is encoded by the SOCS3gene.[1][2]
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 SOCS3 gene is induced by various cytokines, including IL6, IL10, and interferon (IFN)-gamma.
For signaling of IL-6, Epo, GCSF and Leptin, binding of SOCS3 to the respective cytokine receptor has been found to be crucial for the inhibitory function of SOCS3.
Studies of the mouse counterpart of this gene suggested the roles of this gene in the negative regulation of fetal liver hematopoiesis, and placental development.[5]
The SOCS3 protein can bind to JAK2 kinase, and inhibits the activity of JAK2 kinase.
