STK19（serine/threonine kinase 19），癌症关联基因，基因ID：8859，该基因编码丝氨酸/苏氨酸激酶，主要定位于细胞核其具体功能尚不清楚；该蛋白的磷酸化可能参与转录调控。该基因定位于6号染色体上的主要组织相容性复合体（mhc）Ⅲ类区域，表达两个转录变体。[由RefSeq提供，2008年7月]This gene encodes a serine/threonine kinase which localizes predominantly to the nucleus. Its specific function is unknown; it is possible that phosphorylation of this protein is involved in transcriptional regulation. This gene localizes to the major histocompatibility complex (MHC) class III region on chromosome 6 and expresses two transcript variants. [provided by RefSeq， Jul 2008]。
