Kif21a Gene Summary [Rat]
Predicted to enable several functions, including ATP hydrolysis activity; ankyrin repeat binding activity; and plus-end-directed microtubule motor activity. Involved in anterograde axonal transport. Is active in presynapse. Human ortholog(s) of this gene implicated in congenital fibrosis of the extraocular muscles 1. Orthologous to human KIF21A (kinesin family member 21A).

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 rat Kif21a often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
