Summary

KIFC2 (kinesin family member C2, HGNC:29530) is a protein-coding gene on chromosome 8q24.3, encoding Kinesin-like protein KIFC2 (Q96AC6). May play a role in microtubule-dependent retrograde axonal transport.

Predicted to enable ATP hydrolysis activity; microtubule binding activity; and plus-end-directed microtubule motor activity. Predicted to be involved in anterograde dendritic transport of neurotransmitter receptor complex; axon guidance; and synaptic vesicle transport. Predicted to be located in cytoskeleton and dendrite cytoplasm. Predicted to be part of kinesin complex. Predicted to be active in cytoplasm and microtubule.
