摘要

ERBB家族成员表皮受体酪氨酸激酶(EGFR)由28个外显子和27个内含子组成。EGFR编码11个转录本，其中8个为蛋白质编码。EGFR是一种跨膜糖蛋白，可以被几种不同的配体激活，如表皮生长因子(EGF)、转化生长因子- α (TGFA)、肝素结合的EGF样生长因子(HBEGF)、β -纤维素蛋白(BTC)、双调节蛋白(AREG)、表调节蛋白(EREG)和表原(EPGN) (Singh, 2016)。配体结合诱导EGFR二聚化和自磷酸化，随后是一系列下游磷酸化事件(Capuani et al.， 2015)。EGFR激活在细胞存活、增殖、迁移和分化中起着关键作用(Purba, 2017)。

EGFR (Epidermal Growth Factor Receptor)

ERBB family member epidermal receptor tyrosine kinase (EGFR) is composed of 28 exons and 27 introns. EGFR codes for 11 transcripts and 8 of them are protein coding. EGFR is a transmembrane glycoprotein that can be activated by several different ligands such as epidermal growth factor (EGF), transforming growth factor-alpha (TGFA), heparin-binding EGF-like growth factor (HBEGF), betacellulin (BTC), amphiregulin (AREG), epiregulin (EREG), and epigen (EPGN) (Singh, 2016). Ligand binding induces the dimerization of EGFR and autophosphorylation followed by a cascade of downstream phosphorylation events (Capuani et al., 2015). EGFR activation plays a key role in cell survival, proliferation, migration and differentiation (Purba, 2017).
