Predicted to enable kinesin binding activity. Involved in neuron projection development. Located in mitochondrial membrane and neuron projection. Is expressed in gut; nervous system; and sensory organ. Used to study Cayman type cerebellar ataxia. Human ortholog(s) of this gene implicated in Cayman type cerebellar ataxia and cerebellar ataxia. Orthologous to human ATCAY (ATCAY kinesin light chain interacting caytaxin). [provided by Alliance of Genome Resources, Apr 2022]
