整合素β-4 (GP150) (CD抗原 CD104)

P16144

功能描述

整联蛋白alpha-6/beta-4是层粘连蛋白的受体。在上皮细胞的半桥粒中起关键的结构作用。是调节角质形成细胞极性和运动性所必需的。ITGA6:ITGB4结合NRG1(通过EGF结构域),这种结合对于NRG1-ERBB信号传导至关重要(PubMed:20682778)。ITGA6:ITGB4结合IGF1,这种结合对于IGF1信号传导至关重要(PubMed:22351760)。ITGA6:ITGB4结合IGF2,这种结合对于IGF2信号传导至关重要(PubMed:28873464)。 {ECO:0000269|PubMed:12482924, ECO:0000269|PubMed:19403692, ECO:0000269|PubMed:20682778, ECO:0000269|PubMed:22351760, ECO:0000269|PubMed:28873464}。

组织特异性

Integrin alpha-6/beta-4 is predominantly expressed by epithelia. Isoform beta-4D is also expressed in colon and placenta. Isoform beta-4E is also expressed in epidermis, lung, duodenum, heart, spleen and stomach.
