PHYSICAL PROPERTIES

STRUCTURE

motifs/domains	one kinesin motor domain
	one FHA domain
	one pleckstrin homology (PH) domain at C terminus, lacking a motor domain

HOMOLOGY

interspecies

homolog to murine Kf1b

intraspecies

homolog to ATSV (KIF1A)

Homologene

FAMILY	kinesin-like protein family
	UNC104 subfamily
	Kinesin-3 family

CATEGORY

motor/contractile , tumor suppressor , transport

SUBCELLULAR LOCALIZATION	intracellular
	intracellular,cytoplasm,organelle,mitochondria
	intracellular,cytoplasm,cytosolic,vesicle
	intracellular,cytoplasm,cytoskeleton,microtubule

basic FUNCTION	involved in transport of synaptic vesicle precursors, in the anterograde transport of mitochondria
	kinesin superfamily member involved in the transport of organelles and vesicles
	motor proteins implicated in anterograde transport of mitochondria and synaptic vesicle precursors
	STARD13 and KIF1B are thus central components of a signalling network that guides spindle positioning, cell-cell adhesion and mitotic fidelity

CELLULAR PROCESS	cell life, differentiation

PHYSIOLOGICAL PROCESS

mitochondrial transport

text	neuronal differentiation and survival

PATHWAY

metabolism

signaling

a component

INTERACTION

DNA

RNA

small molecule

protein	bound to the specific region of KIF1B (813-916 aa), but not to other kinesin family members
	XAF1 is likely a downstream target of KIF1B beta
