PDGFRB(血小板衍生生长因子受体β)是一种编码跨膜酪氨酸激酶受体的基因,属于血小板衍生生长因子受体(PDGFR)家族,该家族还包括PDGFRA。PDGFR家族成员在细胞增殖、迁移和存活中起关键作用,主要通过结合PDGF配体(如PDGF-BB)激活下游信号通路(如PI3K-AKT和RAS-MAPK)。PDGFRB主要在血管平滑肌细胞、周细胞和成纤维细胞中表达,参与血管发育和组织修复。突变或异常表达会导致功能失调,例如PDGFRB的激活突变(如D849V)与某些癌症(如胃肠道间质瘤)和罕见疾病(如早发性婴儿肌纤维瘤病)相关。过表达PDGFRB可能导致异常细胞增殖和血管生成,促进肿瘤生长和转移;而表达降低则可能影响血管稳定性和组织修复能力。PDGFRB还与特发性肺纤维化和动脉粥样硬化等疾病有关。该基因家族的特点是具有胞外免疫球蛋白样结构域、跨膜区和胞内酪氨酸激酶结构域,通过二聚化和自磷酸化激活下游信号。靶向PDGFRB的药物(如伊马替尼)已用于治疗相关疾病。
This gene encodes a cell surface tyrosine kinase receptor for members of the platelet-derived growth factor family. These growth factors are mitogens for cells of mesenchymal origin. The identity of the growth factor bound to a receptor monomer determines whether the functional receptor is a homodimer or a heterodimer, composed of both platelet-derived growth factor receptor alpha and beta polypeptides. This gene is flanked on chromosome 5 by the genes for granulocyte-macrophage colony-stimulating factor and macrophage-colony stimulating factor receptor; all three genes may be implicated in the 5-q syndrome. A translocation between chromosomes 5 and 12, that fuses this gene to that of the translocation, ETV6, leukemia gene, results in chronic myeloproliferative disorder with eosinophilia.
