Kif1a Gene Summary [Rat]
Enables identical protein binding activity and microtubule binding activity. Involved in several processes, including interkinetic nuclear migration; regulation of dendritic spine morphogenesis; and transport along microtubule. Located in several cellular components, including microtubule; neuronal cell body; and secretory vesicle. Part of protein-containing complex. Is active in glutamatergic synapse and postsynapse. Biomarker of synucleinopathy. Human ortholog(s) of this gene implicated in NESCAV syndrome; hereditary sensory neuropathy; hereditary sensory neuropathy type 2C; hereditary spastic paraplegia; and hereditary spastic paraplegia 30. Orthologous to human KIF1A (kinesin family member 1A). [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 rat Kif1a often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
