Previous GeneCards Identifiers for CISH Gene
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 IL2, IL3, 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. Multiple transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Aug 2008]
GeneCards Summary for CISH Gene
CISH (Cytokine Inducible SH2 Containing Protein) is a Protein Coding gene. Diseases associated with CISH include Bacteremia 2 and Malaria. Among its related pathways are IL-2 Signaling Pathway and Prolactin Signaling Pathway. Gene Ontology (GO) annotations related to this gene include protein kinase inhibitor activity. An important paralog of this gene is SOCS2.
UniProtKB/Swiss-Prot Summary for CISH Gene
SOCS family proteins form part of a classical negative feedback system that regulates cytokine signal transduction. CIS is involved in the negative regulation of cytokines that signal through the JAK-STAT5 pathway such as erythropoietin, prolactin and interleukin 3 (IL3) receptor. Inhibits STAT5 trans-activation by suppressing its tyrosine phosphorylation. May be a substrate-recognition component of a SCF-like ECS (Elongin BC-CUL2/5-SOCS-box protein) E3 ubiquitin-protein ligase complex which mediates the ubiquitination and subsequent proteasomal degradation of target proteins (By similarity).
