Summary

KIF5B (kinesin family member 5B, HGNC:6324) is a protein-coding gene on chromosome 10p11.22, encoding Kinesin-1 heavy chain (P33176). Microtubule-dependent motor required for normal distribution of mitochondria and lysosomes.

Enables identical protein binding activity; microtubule binding activity; and microtubule motor activity. Involved in several processes, including natural killer cell mediated cytotoxicity; positive regulation of protein localization to plasma membrane; and vesicle transport along microtubule. Located in several cellular components, including centriolar satellite; cytosol; and nuclear membrane.

Function. 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. 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. Required for anterograde axonal transportation of MAPK8IP3/JIP3 which is essential for MAPK8IP3/JIP3 function in axon elongation. 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.

Subunit / interactions. Oligomer composed of two heavy chains and two light chains. Interacts with GRIP1 and PPP1R42. Interacts with SYBU. Interacts with JAKMIP1. Interacts with PLEKHM2. Interacts with ECPAS. Interacts with ZFYVE27. Found in a complex with OGT, RHOT1, RHOT2 and TRAK1. Interacts with APP (via cytoplasmic domain).

Subcellular location. Cytoplasm. Cytoskeleton. Cytolytic granule membrane. Lysosome membrane.

Domain organisation. Composed of three structural domains: a large globular N-terminal domain which is responsible for the motor activity of kinesin (it hydrolyzes ATP and binds microtubule), a central alpha-helical coiled coil domain that mediates the heavy chain dimerization; and a small globular C-terminal domain which interacts with other proteins (such as the kinesin light chains), vesicles and membranous organelles.

Similarity. Belongs to the TRAFAC class myosin-kinesin ATPase superfamily. Kinesin family. Kinesin subfamily.

Reactome pathways and GO biological processes over-represented among this gene’s 165 IntAct physical interaction partners (hypergeometric vs the genome-wide background, BH-FDR, gene-set size 15–500, ranked by fold). A functional readout of the neighbourhood — distinct from this gene’s own memberships above, and biased toward well-studied / hub proteins, so read it as themes rather than proof.
