Nek2 Gene Summary [Mouse]
Enables protein kinase activity. Acts upstream of or within blastocyst development; mitotic spindle assembly; and protein phosphorylation. Located in condensed nuclear chromosome; midbody; and spindle pole. Is expressed in several structures, including alimentary system; central nervous system; genitourinary system; hemolymphoid system; and respiratory system. Human ortholog(s) of this gene implicated in retinitis pigmentosa 67. Orthologous to human NEK2 (NIMA related kinase 2). [provided by Alliance of Genome Resources, Jul 2025]

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 Nek2 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
