Disease

STK19_HUMAN Gain-of-function variants in STK19 are involved in NRAS-driven melanomagenesis (PubMed:30712867). Melanoma are malignant neoplasm of melanocytes, arising de novo or from a pre-existing benign nevus, which occurs most often in the skin but may also involve other sites (PubMed:30712867). Conditional knockin mice overexpressing Asn-89 variant exhibit hyperpigmentation of the skin, ears, and tail, and the melanin content in skin was significantly increased after tamoxifen induction (PubMed:30712867). Moreover, knockin mice overexpressing Asn-89 variant promote NRAS 'Arg-61'-driven melanomagenesis (PubMed:30712867).^[1]

Function

STK19_HUMAN Serine/threonine-protein kinase that acts as a key regulator of NRAS signaling by mediating phosphorylation of NRAS at 'Ser-89', thereby enhancing NRAS-binding to its downstream effectors.^[2]
