NECTIN2 (Nectin Cell Adhesion Molecule 2): NECTIN2, also known as CD112, is a transmembrane cell adhesion molecule that belongs to the nectin family. It plays a pivotal role in mediating cell-cell adhesion and is predominantly expressed in epithelial and neuronal tissues. NECTIN2 functions as a homophilic and heterophilic adhesion molecule, interacting with other nectins and nectin-like proteins, as well as with receptors on neighboring cells, such as DNAM-1 (CD226), CD96, and TIGIT. Through these interactions, NECTIN2 contributes to the formation and maintenance of adherens junctions and synaptic connections, thereby regulating processes such as cell migration, polarization, and synaptic transmission.
