Kif1b Gene Summary [Mouse]
Enables plus-end-directed microtubule motor activity. Involved in chemical synaptic transmission and organelle transport along microtubule. Located in mitochondrion. Is active in postsynapse and synaptic vesicle membrane. Is expressed in several structures, including alimentary system; brain; genitourinary system; hemolymphoid system; and skeletal musculature. Used to study Charcot-Marie-Tooth disease type 2A1. Human ortholog(s) of this gene implicated in Charcot-Marie-Tooth disease type 2A1; hepatocellular carcinoma; multiple sclerosis; neuroblastoma; and ovary epithelial cancer. Orthologous to human KIF1B (kinesin family member 1B). [provided by Alliance of Genome Resources, Jul 2025]

Protein Domains
A protein domain is a distinct structural or functional region within a protein that can evolve, function, and exist independently of the rest of the protein chain. These domains in mouse Kif1b often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
