Nectin-3/CD113 蛋白, Human (400a.a, HEK293, His)

Nectin-3/CD113 is a multifunctional cell adhesion protein that mediates cell-cell interactions through heterophilic trans binding to nectin-like proteins or nectins. It interacts with NECTIN2 at the Sertoli cell-spermatocyte junction and triggers CDC42 and RAC small G protein activation through common signaling molecules such as SRC and RAP1. Nectin-3/CD113 Protein, Human (400a.a, HEK293, His) is the recombinant human-derived Nectin-3/CD113 protein, expressed by HEK293 , with C-His labeled tag. The total length of Nectin-3/CD113 Protein, Human (400a.a, HEK293, His) is 400 a.a., with molecular weight of 65-75 kDa.

Nectin-3/CD113 是一种多功能细胞粘附蛋白，通过与 Nectin 样蛋白或 Nectin 的异嗜性反式结合，在介导细胞间相互作用中发挥着关键作用，其在支持精细胞连接处与 NECTIN2 的相互作用就是例证。这种与 PVR 的反式相互作用触发了 CDC42 和 RAC 小 G 蛋白的激活，由 SRC 和 RAP1 等常见信号分子介导。除了参与粘附连接和突触之外，Nectin-3/CD113 还可诱导细胞表面内吞作用介导的 PVR 下调，从而导致细胞运动和增殖减少。此外，它还有助于睫状体的形态，并与各种蛋白质（包括 NECTIN1、NECTIN2、PVR、IGSF4B/Necl-1 和 IGSF4）形成顺式和反式同二聚体以及反式异二聚体。NECTIN1 和 NECTIN3 在突触前和突触后位点的相互作用启动了轴突和树突之间粘着点连接的形成。此外，Nectin-3/CD113 以低亲和力与 TIGIT 结合，并与 AFDN 相互作用，建立与肌动蛋白细胞骨架的连接。
