INPP5D(inositol polyphosphate-5-phosphatase D),癌症关联基因,基因ID:3635,该基因是肌醇多磷酸-5-磷酸酶(inpp5)家族的一员,编码一个具有n末端sh2结构域、肌醇磷酸酶结构域和两个c末端蛋白质相互作用结构域的蛋白质。这种蛋白的表达仅限于造血细胞,其从胞浆到质膜的运动是由酪氨酸磷酸化介导的在质膜上,蛋白质从磷脂酰肌醇(3,4,5)-三磷酸和肌醇-1,3,4,5-四磷酸水解5'磷酸,从而影响多种信号通路。该蛋白也部分定位于细胞核,可能参与核磷酸肌醇信号传导过程。总的来说,该蛋白是骨髓细胞增殖和存活的负调控因子。这种基因的突变与免疫系统的缺陷和癌症有关。该基因的选择性剪接导致多个转录变体。[由RefSeq提供,2014年2月]This gene is a member of the inositol polyphosphate-5-phosphatase (INPP5) family and encodes a protein with an N-terminal SH2 domain, an inositol phosphatase domain, and two C-terminal protein interaction domains. Expression of this protein is restricted to hematopoietic cells where its movement from the cytosol to the plasma membrane is mediated by tyrosine phosphorylation. At the plasma membrane, the protein hydrolyzes the 5' phosphate from phosphatidylinositol (3,4,5)-trisphosphate and inositol-1,3,4,5-tetrakisphosphate, thereby affecting multiple signaling pathways. The protein is also partly lo。
