血小板衍生生长因子受体

血小板衍生生长因子受体(Platelet-derived growth factor receptors,PDGF-R)为血小板衍生生长因子(PDGF)蛋白质家族的受体,位于细胞膜表面,属于酪胺酸激酶受体英语receptor tyrosine kinase的一种。PDGF的次单元A次单元B在调控细胞增殖分化生长发育上扮演相当重要的角色。如果调控不正常,可能会引发癌症等多种疾病。[2]

PDGF-R有两种型态,分别为AB,两种型态来自于不同基因。[3]由于PDRF-R必须由两者结合成为双体之后才能作用,因此PDGFRA和PDGFRB可以互相组合或自我组合为均聚物(homodimerizes,即A配A、B配B)或杂二聚物(heterodimerizes,即A配B)[4]
