About KLRC1

Cytogenetic location: 12p13.2 Genomic coordinates (GRCh38): 12:10,442,264-10,454,685 (from NCBI)

This gene has 7 transcripts (splice variants), 676 orthologues and 23 paralogues. Broad expression in spleen (RPKM 1.5), endometrium (RPKM 1.3) and 21 other tissues.

Summary

Natural killer (NK) cells are lymphocytes that can mediate lysis of certain tumor cells and virus-infected cells without previous activation. They can also regulate specific humoral and cell-mediated immunity. The protein encoded by this gene belongs to the killer cell lectin-like receptor family, also called NKG2 family, which is a group of transmembrane proteins preferentially expressed in NK cells. This family of proteins is characterized by the type II membrane orientation and the presence of a C-type lectin domain. This protein forms a complex with another family member, KLRD1/CD94, and has been implicated in the recognition of the MHC class I HLA-E molecules in NK cells. The genes of NKG2 family members form a killer cell lectin-like receptor gene cluster on chromosome 12. Multiple alternatively spliced transcript variants encoding distinct isoforms have been observed. [provided by RefSeq, Jan 2015]
