DESCRIPTION

Also known as KINH_RAT, Kif5b, Khc. Microtubule-dependent motor required for normal distribution of mitochondria and lysosomes. Can induce formation of neurite-like membrane protrusions in non-neuronal cells in a ZFYVE27-dependent manner (By similarity). Regulates centrosome and nuclear positioning during mitotic entry. During the G2 phase of the cell cycle in a BICD2-dependent manner, antagonizes dynein function and drives the separation of nuclei and centrosomes (By similarity). Required for anterograde axonal transportation of MAPK8IP3/JIP3 which is essential for MAPK8IP3/JIP3 function in axon elongation (PubMed:23576431). Through binding with PLEKHM2 and ARL8B, directs lysosome movement toward microtubule plus ends. Involved in NK cell-mediated cytotoxicity. Drives the polarization of cytolytic granules and microtubule-organizing centers (MTOCs) toward the immune synapse between effector NK lymphocytes and target cells (By similarity). Oligomer composed of two heavy chains and two light chains. Interacts with GRIP1 and PPP1R42 (By similarity). Interacts with SYBU. Interacts with JAKMIP1. Interacts with PLEKHM2. Interacts with ECPAS (By similarity). Interacts with ZFYVE27 (By similarity). Found in a complex with OGT, RHOT1, RHOT2 and TRAK1 (PubMed:24995978). Interacts with APP (via cytoplasmic domain) (PubMed:23011729).
