Nectin-4 (连接蛋白细胞粘附分子-4)

Nectin-4 is a cell adhesion molecule that plays a crucial role in cell-cell adhesion and communication. Nectin-4 is involved in various physiological processes such as embryonic development and tissue homeostasis. Nectin-4 is overexpressed on the surface of tumor cells, making it an attractive target for cancer therapy. Nectin-4 belongs to the nectin family of proteins, which is characterized by immunoglobulin-like domains and plays important roles in mediating cell-cell interactions through homophilic and heterophilic binding^[1][2][3].
