Gene locus:

16p13.13

Protein name:

Suppressor of cytokine signaling 1

Protein Size:

211 amino acids; about 24 kDa

Function:

The protein encoded by SOCS1 is a member of the STAT-induced STAT inhibitor (SSI), also known as suppressor of cytokine signaling (SOCS), family. Members of this family are cytokine-inducible negative regulators of cytokine signaling. The SOCS1 protein is rapidly induced following stimulation by several type I and type II cytokines (including IL2, IL3 erythropoietin (EPO), CSF2/GM-CSF, and interferon (IFN)-gamm), and it attenuates their signaling by its ability to bind and inhibit all four of the Janus family of intracellular tyrosine kinases (JAKs).

Cancer-related alterations:

Somatic SOCS1 mutations have been found in tumors from haematopoietic and lymphoid tissue. Mutations in classical Hodgkin lymphoma and primary mediastinal B-cell lymphoma are frequent. Deletions as well as point mutations are observed. There are no mutational hot spots.
