ID:KIF1A_HUMAN DESCRIPTION: RecName: Full=Kinesin-like protein KIF1A; AltName: Full=Axonal transporter of synaptic vesicles; AltName: Full=Microtubule-based motor KIF1A; AltName: Full=Unc-104- and KIF1A-related protein; Short=hUnc-104; FUNCTION: Motor for anterograde axonal transport of synaptic vesicle precursors (By similarity). SUBUNIT: Monomer. Interacts with PPFIA1 and PPFIA4 (By similarity). SUBCELLULAR LOCATION: Cytoplasm, cytoskeleton. Note=Expressed in distal regions of neurites. TISSUE SPECIFICITY: Expressed in neurons. DISEASE: Defects in KIF1A are the cause of spastic paraplegia autosomal recessive type 30 (SPG30) [MIM:610357]. SPG30 is a form of spastic paraplegia, a neurodegenerative disorder characterized by a slow, gradual, progressive weakness and spasticity of the lower limbs. Rate of progression and the severity of symptoms are quite variable. Initial symptoms may include difficulty with balance, weakness and stiffness in the legs, muscle spasms, and dragging the toes when walking. In some forms of the disorder, bladder symptoms (such as incontinence) may appear, or the weakness and stiffness may spread to other parts of the body. SPG30 is characterized by onset in the first or second decades of unsteady spastic gait and hyperreflexia of the lower limbs. DISEASE: Defects in KIF1A are the cause of hereditary sensory neuropathy type 2C (HSN2C) [MIM:614213]. HSN2C is a neurodegenerative disorder characterized by onset in the first decade of progressive distal sensory loss leading to ulceration and amputation of the fingers and toes. Affected individuals also develop distal muscle weakness, primarily affecting the lower limbs. DISEASE: Defects in KIF1A are the cause of mental retardation autosomal dominant type 9 (MRD9) [MIM:614255]. Mental retardation is characterized by significantly below average general intellectual functioning associated with impairments in adaptative behavior and manifested during the developmental period. SIMILARITY: Belongs to the kinesin-like protein family. Unc-104 subfamily. SIMILARITY: Contains 1 FHA domain. SIMILARITY: Contains 1 kinesin-motor domain. SIMILARITY: Contains 1 PH domain. SEQUENCE CAUTION: Sequence=AAB97363.1; Type=Erroneous initiation; Note=Translation N-terminally extended; Sequence=BAE06111.1; Type=Erroneous initiation; Note=Translation N-terminally shortened; Sequence=BAE06111.1; Type=Miscellaneous discrepancy; Note=Probable cloning artifact leading to C-terminal exon with non-canonical splice junction;
The RNAfold program from the Vienna RNA Package is used to perform the secondary structure predictions and folding calculations. The estimated folding energy is in kcal/mol. The more negative the energy, the more secondary structure the RNA is likely to have.

The pictures above may be empty if there is no ModBase structure for the protein. The ModBase structure frequently covers just a fragment of the protein. You may be asked to log onto ModBase the first time you click on the pictures. It is simplest after logging in to just click on the picture again to get to the specific info on that model.
Orthologous Genes in Other Species
Orthologies between human, mouse, and rat are computed by taking the best BLASTP hit, and filtering out non-syntenic hits. For more distant species reciprocal-best BLASTP hits are used. Note that the absence of an ortholog in the table below may reflect incomplete annotations in the other species rather than a true absence of the orthologous gene.
