Summaries for SIRPG Gene

Entrez Gene Summary for SIRPG Gene

  • The protein encoded by this gene is a member of the signal-regulatory protein (SIRP) family, and also belongs to the immunoglobulin superfamily. SIRP family members are receptor-type transmembrane glycoproteins known to be involved in the negative regulation of receptor tyrosine kinase-coupled signaling processes. Alternatively spliced transcript variants encoding different isoforms have been described. [provided by RefSeq, Jul 2008]

GeneCards Summary for SIRPG Gene

SIRPG (Signal Regulatory Protein Gamma) is a Protein Coding gene. Among its related pathways are Platelet activation, signaling and aggregation and Cell surface interactions at the vascular wall. An important paralog of this gene is SIRPA.

UniProtKB/Swiss-Prot for SIRPG Gene

  • Probable immunoglobulin-like cell surface receptor. On binding with CD47, mediates cell-cell adhesion. Engagement on T-cells by CD47 on antigen-presenting cells results in enhanced antigen-specific T-cell proliferation and costimulates T-cell activation.
