MET基因编码肝细胞生长因子受体(HGFR),是一种受体酪氨酸激酶,属于RTK(受体酪氨酸激酶)基因家族。该基因在胚胎发育、组织修复和伤口愈合中起关键作用,主要通过与配体肝细胞生长因子(HGF)结合激活下游信号通路(如RAS-MAPK、PI3K-AKT),调控细胞增殖、迁移和存活。MET在肝脏、肾脏和肌肉等组织中高表达,其功能异常与多种癌症密切相关,如肝癌、胃癌和肺癌。MET突变(如外显子14跳跃突变)会导致受体持续激活,促进肿瘤生长和转移;而基因扩增则引发过表达,增强侵袭性。降低MET表达会抑制肿瘤进展,但可能影响正常组织修复。MET属于MET原癌基因家族,该家族成员均具有酪氨酸激酶活性,参与细胞信号转导和生长调控。靶向MET的药物(如克唑替尼)已用于治疗携带MET异常的癌症。
The proto-oncogene MET product is the hepatocyte growth factor receptor and encodes tyrosine-kinase activity. The primary single chain precursor protein is post-translationally cleaved to produce the alpha and beta subunits, which are disulfide linked to form the mature receptor. Various mutations in the MET gene are associated with papillary renal carcinoma. Two transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Jul 2008]
原癌基因MET产品是肝细胞生长因子受体和编码酪氨酸激酶的活性。主单链前体蛋白质是翻译后切割产生的α和β亚基,它是二硫键连接以形成成熟受体。在MET基因的各种突变与乳头状肾癌有关。已发现该基因编码不同亚型的两个转录变异体。 [由RefSeq的,2008年7月提供]
