Protein: Kinesin-like protein KIF1A (EC 5.6.1.3) (Axonal transporter of synaptic vesicles) (Microtubule-based motor KIF1A) (Unc-104- and KIF1A-related protein) (hUnc-104) (Q12756)
Organism: Homo sapiens (Human)
Function: Motor for anterograde axonal transport of synaptic vesicle precursors. Also required for neuronal dense core vesicles (DCVs) transport to the dendritic spines and axons. The interaction calcium-dependent with CALM1 increases vesicle motility and interaction with the scaffolding proteins PPFIA2 and TANC2 recruits DCVs to synaptic sites.
Subcellular location: Cytoplasm, cytoskeleton {ECO:0000269|PubMed:21376300}. Cell projection, neuron projection {ECO:0000269|PubMed:25265257, ECO:0000269|PubMed:32652677, ECO:0000269|PubMed:33880452}. Cell projection, axon {ECO:0000250|UniProtKB:P33173}.

Cytoplasmic vesicle, secretory vesicle, neuronal dense core vesicle membrane {ECO:0000250|UniProtKB:F1M4A4}; Peripheral membrane protein {ECO:0000250|UniProtKB:F1M4A4}; Cytoplasmic side {ECO:0000250|UniProtKB:F1M4A4}. Note=Within neuronal cells concentrated in the axon, with smaller amounts in the perinuclear and synaptic regions (By similarity). Accumulates at the distal tip of growing neurites. {ECO:0000250|UniProtKB:P33173, ECO:0000269|PubMed:25265257, ECO:0000269|PubMed:33880452}.
