FGFR系列蛋白

 
 
 
FGFR(Fibroblast Growth Factor Receptors),即成纤维细胞生长因子受体,一般包括FGFR1-4(也称CD331-334)四种类型。FGFR是酪氨酸酶受体家族的一支,为I型跨膜蛋白,包括胞外区、跨膜区和胞质区,通常以二聚体形式发挥作用。其中,胞外结构域包含三个Ig样区域D1(IgI)、D2(IgII)、D3(IgIII),其中D1和Acidic box组成自抑制区;D2和D3负责与配体结合(D2与细胞表面硫酸乙酰肝素结合,D3由于可变剪接有IIIb和IIIc两种形式,FGFR4中目前只发现IIIc一种亚型)。根据Ig样结构域的个数,FGFR可分为两种形式,一种是α型,含有IgI, IgII, IgIII三个区域;另一种是β型,只含IgII和IgIII。
FGFR结构(Babina IS, et al., 2017
FGFR的配体为FGF,目前已发现的人FGF有18种,除了FGF19、FGF21、FGF23是内分泌外,其余皆为旁分泌产生,其中FGF7只能与IIIb型的FGFR2结合。FGFR与FGF结合介导了RAS-RAF-MAPK、PI3K-AKT、JAK-STAT以及PLCγ等信号通路的激活传递,参与细胞生长、分化、迁移、新血管生成、调节器官发育和伤口愈合等重要生理过程。FGFR基因变异通常在肺癌、肝癌、肝内胆管癌、乳腺癌、胃癌、子宫癌及膀胱癌等实体瘤中广泛存在,并且不同癌种的FGFR突变类型及频率也存在差异。
