DESCRIPTION

Also known as KIF5A_HUMAN, KIF5A, NKHC1. Microtubule-dependent motor required for slow axonal transport of neurofilament proteins (NFH, NFM and NFL). Can induce formation of neurite-like membrane protrusions in non-neuronal cells in a ZFYVE27-dependent manner. The ZFYVE27-KIF5A complex contributes to the vesicular transport of VAPA, VAPB, SURF4, RAB11A, RAB11B and RTN3 proteins in neurons. Required for anterograde axonal transportation of MAPK8IP3/JIP3 which is essential for MAPK8IP3/JIP3 function in axon elongation. Oligomer composed of two heavy chains and two light chains. Interacts with GRIP1. Interacts with FMR1 (via C-terminus); this interaction is increased in a mGluR-dependent manner. Interacts with ZFYVE27. Interacts with VAPA, VAPB, SURF4, RAB11A (GDP-bound form), RAB11B (GDP-bound form) and RTN3 in a ZFYVE27-dependent manner (By similarity). Interacts with BORCS5 (PubMed:25898167). Interacts with BICD2 (PubMed:20386726). Interacts with DTNB (By similarity).
