Nectin2 Gene Summary [Mouse]
Enables cell adhesion molecule binding activity and protein homodimerization activity. Involved in homophilic cell adhesion via plasma membrane adhesion molecules and spermatid development. Acts upstream of or within several processes, including establishment of mitochondrion localization; sperm mitochondrion organization; and spermatid development. Located in cell-cell contact zone; plasma membrane; and zonula adherens. Is expressed in brain; cochlea; enamel organ; male reproductive system; and metanephros. Human ortholog(s) of this gene implicated in Alzheimer's disease and multiple sclerosis. Orthologous to human NECTIN2 (nectin cell adhesion molecule 2).

Protein Domains
A protein domain is a distinct structural or functional region within a protein that can evolve, function, and exist independently of the rest of the protein chain. These domains in mouse Nectin2 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
