Kif1a Gene Summary [Mouse]
Enables microtubule binding activity and plus-end-directed microtubule motor activity. Involved in anterograde synaptic vesicle transport. Located in neuron projection and neuronal cell body. Is expressed in central nervous system; genitourinary system; peripheral nervous system ganglion; sensory organ; and trigeminal nerve. Used to study hereditary spastic paraplegia 30. 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 mouse 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.
