KIF5A explained

Kinesin family member 5A is a protein that in humans is encoded by the KIF5A gene. It is part of the kinesin family of motor proteins.[1] [2] [3]

This gene encodes a member of the kinesin family of proteins. Members of this family are part of a multi-subunit complex that functions as a microtubule motor in intracellular organelle transport. Mutations in this gene cause autosomal dominant spastic paraplegia 10.[3]

Interactions

KIF5A has been shown to interact with KLC1.[4] [5]

Clinical significance

Mutations in KIF5A have been reported to cause hereditary spastic paraplegia type 10 (SPG1).[6]

Mutations in KIF5A have also been found to cause amyotrophic lateral sclerosis.[7]

KIF5A has been shown to play a role in Alzheimer's disease by modulating the toxic effect of beta-amyloid on axonal transport of mitochondria.[8]
