Organism: Homo sapiens
Lineage: Eukaryota; Metazoa; Chordata; Craniata; Vertebrata; Euteleostomi; Mammalia; Eutheria; Euarchontoglires; Primates; Haplorrhini; Catarrhini; Hominidae; Homo
Also known as: CD172g; SIRPB2; SIRP-B2; bA77C3.1; SIRPgamma
Summary: 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]

Title: Genetic Control of Splicing at SIRPG Modulates Risk of Type 1 Diabetes.
Altered expression of SIRPgamma on the T-cells of relapsing remitting multiple sclerosis and type 1 diabetes patients could potentiate effector responses from T-cells.
Title: Altered expression of SIRPγ on the T-cells of relapsing remitting multiple sclerosis and type 1 diabetes patients could potentiate effector responses from T-cells.
The SNP rs2281808 TT variant reduced SIRPgamma expression on T-cells. SIRPgamma(low) CD8 T-cells in CT and TT individuals were in a heightened effector state with lower activation threshold and had greater gene expression of molecules associated with migratory and cytotoxic potential. SIRPgamma(low) CD8 T-cells were deficient in transcription factors associated with long-term functional memory formation.

SIRPgamma in complex with FabOX117 forms a dimer in the crystal. Binding to the Fab fixes the position of domain 1 relative to domains 2/3 exposing a surface which favours formation of a homotypic dimer.

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
