Summaries for KLRC1 Gene

Entrez Gene Summary for KLRC1 Gene

  • 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]

GeneCards Summary for KLRC1 Gene

KLRC1 (Killer Cell Lectin Like Receptor C1) is a Protein Coding gene. Diseases associated with KLRC1 include Bare Lymphocyte Syndrome, Type I and Vulvar Intraepithelial Neoplasia. Among its related pathways are Immunoregulatory interactions between a Lymphoid and a non-Lymphoid cell and Immune response_Role of integrins in NK cells cytotoxicity. GO annotations related to this gene include transmembrane signaling receptor activity and MHC class I protein complex binding. An important paralog of this gene is KLRC2.
