Tpx2 Gene Summary [Mouse]
Enables importin-alpha family protein binding activity and protein kinase binding activity. Involved in mitotic spindle assembly and regulation of mitotic spindle organization. Located in axon hillock and spindle. Is expressed in cerebral cortex ventricular layer; large intestine; nephrogenic zone; and small intestine. Orthologous to human TPX2 (TPX2 microtubule nucleation factor). [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 Tpx2 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
