NECTIN2 (Nectin Cell Adhesion Molecule 2): NECTIN2, also known as CD112, is a transmembrane protein from the nectin family that facilitates cell-to-cell adhesion. It is primarily found in epithelial and neuronal tissues and interacts with other nectins and receptors such as DNAM-1 (CD226), CD96, and TIGIT. NECTIN2 is crucial in the formation and maintenance of adherens junctions and synaptic connections, impacting cell migration, polarization, and synaptic transmission.
