Binding of the ligand activates the cytolytic response of natural killer (NK) cells, CD8 alphabeta T cells, and gammadelta T cells which express the receptor. This protein is stress-induced and is similar to MHC class I molecules; however, it does not associate with beta-2-microglobulin or bind peptides. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Jan 2014]. * **UniProt Summary**: Seems to have no role in antigen presentation. Acts as a stress-induced self-antigen that is recognized by gamma delta T cells. Ligand for the KLRK1/NKG2D receptor. Binding to KLRK1 leads to cell lysis. {ECO:0000269|PubMed:11491531, ECO:0000269|PubMed:11777960, ECO:0000269|PubMed:9497295}. |MHC I| |C1-set| |negative regulation of defense response to virus by host| |gamma-delta T cell activation| |natural killer cell lectin-like receptor binding| |susceptibility to natural killer cell mediated cytotoxicity| |T cell mediated cytotoxicity| |cytolysis| |negative regulation of defense response to virus| |natural killer cell mediated cytotoxicity| |natural killer cell mediated immunity| |positive regulation of natural killer cell mediated cytotoxicity| |positive regulation of natural killer cell mediated immunity| |regulation of defense response to virus by host| |leukocyte mediated cytotoxicity| |T cell mediated immunity| |regulation of natural killer cell mediated cytotoxicity| |regulation of natural killer cell mediated immunity| |positive regulation of leukocyte mediated cytotoxicity| |natural killer cell activation| |positive regulation of cell killing| |regulation of defense response to virus| |regulation of leukocyte mediated cytotoxicity| |cell killing| |negative regulation of response to biotic stimulus| |regulation of cell killing| |positive regulation of lymphocyte mediated immunity| |response to retinoic acid| |response to heat| |negative regulation of immune effector process| |positive regulation of leukocyte mediated immunity| |regulation of lymphocyte mediated immunity| |response to temperature stimulus| |regulation of leukocyte mediated immunity| |negative regulation of defense response| |negative regulation of multi-organism process| |positive regulation of immune effector process| |T cell activation| |lymphocyte mediated immunity| |adaptive immune response based on somatic recombination of immune receptors built from immunoglobulin superfamily domains| |positive regulation of innate immune response| |response to acid chemical| |positive regulation of response to biotic stimulus| |negative regulation of response to external stimulus| |lymphocyte activation| |response to oxidative stress| |external side of plasma membrane| |negative regulation of immune system process| |immune response-activating cell surface receptor signaling pathway| |regulation of innate immune response| |regulation of immune effector process| |positive regulation of defense response| |immune response-regulating cell surface receptor signaling pathway| |positive regulation of multi-organism process| |regulation of response to biotic stimulus| |immune response-activating signal transduction| |immune response-regulating signaling pathway| |positive regulation of response to external stimulus| |adaptive immune response| |cell surface| |activation of immune response| |viral process| |regulation of defense response| |leukocyte mediated immunity| |innate immune response| |regulation of multi-organism process| |symbiotic process| |interspecies interaction between organisms| |response to lipid| |positive regulation of immune response| |leukocyte activation| |defense response to other organism| |cell activation| |immune effector process| |regulation of response to external stimulus| |positive regulation of immune system process| |regulation of immune response| |response to abiotic stimulus| |response to other organism| |response to external biotic stimulus| |response to biotic stimulus| |defense response| |regulation of response to stress| |response to oxygen-containing compound| |extracellular space| |negative regulation of response to stimulus| |regulation of immune system process| |immune response| \\ === CRISPR Data === ^Screen^Score^ |[[:results:exp286|HMS-I2 1μM R06 exp286]]|-1.89| |[[:results:exp347|Cyclosporin-A 0.8μM R07 exp347]]|1.71| ^Gene^Correlation^ |[[:human genes:r:rrm1|RRM1]]|0.569| Global Fraction of Cell Lines Where Essential: 1/739 ^Tissue^Fraction Of Cell Lines Where Essential^ |1290807.0|0/1| |909776.0|0/1| |bile duct|0/28| |blood|0/28| |bone|0/26| |breast|0/33| |central nervous system|0/56| |cervix|0/4| |colorectal|0/17| |esophagus|0/13| |fibroblast|0/1| |gastric|0/16| |kidney|0/21| |liver|0/20| |lung|0/75| |lymphocyte|0/16| |ovary|0/26| |pancreas|0/24| |peripheral nervous system|0/16| |plasma cell|0/15| |prostate|0/1| |skin|0/24| |soft tissue|0/9| |thyroid|0/2| |upper aerodigestive|0/22| |urinary tract|1/29| |uterus|0/5| == Essentiality in NALM6 == * **Essentiality Rank**: 14543 * **Expression level (log2 read counts)**: 5.15 {{:chemogenomics:nalm6 dist.png?nolink |}}
