UniProt Annotation
Function Motor for anterograde transport of mitochondria. Has a microtubule plus end-directed motility. Isoform 2 is required for induction of neuronal apoptosis. {ECO:0000269PubMed:18334619}.
Subcellular Localization Cytoplasmic vesicle {ECO:0000250}. Cytoplasm, cytoskeleton {ECO:0000250}. Mitochondrion {ECO:0000269PubMed:16225668}. Note=Colocalizes with synaptophysin at synaptic cytoplasmic transport vesicles in the neurites of hippocampal neurons. {ECO:0000250}.
Disease Associations Charcot-Marie-Tooth disease 2A1 (CMT2A1) [MIM:118210]: A dominant axonal form of Charcot-Marie-Tooth disease, a disorder of the peripheral nervous system, characterized by progressive weakness and atrophy, initially of the peroneal muscles and later of the distal muscles of the arms. Charcot-Marie-Tooth disease is classified in two main groups on the basis of electrophysiologic properties and histopathology: primary peripheral demyelinating neuropathies (designated CMT1 when they are dominantly inherited) and primary peripheral axonal neuropathies (CMT2). Neuropathies of the CMT2 group are characterized by signs of axonal degeneration in the absence of obvious myelin alterations, normal or slightly reduced nerve conduction velocities, and progressive distal muscle weakness and atrophy. Nerve conduction velocities are normal or slightly reduced. {ECO:0000269PubMed:11389829}. Note=The disease is caused by mutations affecting the gene represented in this entry.Neuroblastoma 1 (NBLST1) [MIM:256700]: A common neoplasm of early childhood arising from embryonic cells that form the primitive neural crest and give rise to the adrenal medulla and the sympathetic nervous system. Note=Disease susceptibility is associated with variations affecting the gene represented in this entry.Pheochromocytoma (PCC) [MIM:171300]: A catecholamine- producing tumor of chromaffin tissue of the adrenal medulla or sympathetic paraganglia. The cardinal symptom, reflecting the increased secretion of epinephrine and norepinephrine, is hypertension, which may be persistent or intermittent. {ECO:0000269PubMed:18334619}. Note=Disease susceptibility is associated with variations affecting the gene represented in this entry.
Tissue Specificity Isoform 3 is abundant in the skeletal muscle. It is also expressed in fetal brain, lung and kidney, and adult heart, placenta, testis, ovary and small intestine. Isoform 2 is abundant in the brain and also expressed in fetal heart, lung, liver and kidney, and adult skeletal muscle, placenta, liver, kidney, heart, spleen, thymus, prostate, testis, ovary, small intestine, colon and pancreas. {ECO:0000269PubMed:10762626, ECO:0000269PubMed:11526494, ECO:0000269PubMed:12888911}.
