Kinesin-like protein KIF1A, also known as axonal transporter of synaptic vesicles or microtubule-based motor KIF1A, is a protein that in humans is encoded by the KIF1A gene.[1][2][3]


KIF1A is a member of the kinesin family. This protein is highly similar to mouse heavy-chain kinesin member 1A protein, which is an anterograde motor protein that transports membranous organelles along axonal microtubules. It is thought that this protein may play a critical role in the development of axonal neuropathies resulting from impaired axonal transport. There are multiple polyadenylation sites found in this gene.[1] Sexual orientation has been linked to the regulatory domain of the gene.[4]

Clinical significance[edit]

KIF1A is associated with hereditary spastic paraparesis.[5]
