CISH (protein) explained

Cytokine-inducible SH2-containing protein is a protein that in humans is encoded by the CISH gene.[1] [2] [3] CISH orthologs[4] have been identified in most mammals with sequenced genomes. CISH controls T cell receptor (TCR) signaling, and variations of CISH with certain SNPs are associated with susceptibility to bacteremia, tuberculosis and malaria.[5]

Function

The protein encoded by this gene contains a SH2 domain and a SOCS box domain. The protein thus belongs to the cytokine-induced STAT inhibitor (CIS), also known as suppressor of cytokine signaling (SOCS) or STAT-induced STAT inhibitor (SSI), protein family. CIS family members are known to be cytokine-inducible negative regulators of cytokine signaling.

The expression of this gene can be induced by IL-2, IL-3, GM-CSF and EPO in hematopoietic cells. Proteasome-mediated degradation of this protein has been shown to be involved in the inactivation of the erythropoietin receptor.

CISH is induced by T cell receptor (TCR) ligation and negatively regulates it by targeting the critical signaling intermediate PLC-gamma-1 for degradation.[6] The deletion of Cish in effector T cells has been shown to augment TCR signaling and subsequent effector cytokine release, proliferation and survival. The adoptive transfer of tumor-specific effector T cells knocked out or knocked down for CISH resulted in a significant increase in functional avidity and long-term tumor immunity. There are no changes in activity or phosphorylation of Cish's purported target, STAT5 in either the presence or absence of Cish.

In human tumor-infiltrating lymphocytes (TIL), CISH expression has been reported to be inversely expressed with known T cell activation/exhaustion markers and regulates their expression and neoantigen reactivity. Combination therapy with checkpoint blockade synergistically results in profound tumor regressing in a pre-clinical tumor model [7]

Interactions

CISH has been shown to interact with IL2RB[8] and Growth hormone receptor.[9] and PLCG1.[6]
