Predicted to enable low voltage-gated calcium channel activity and voltage-gated sodium channel activity. Acts upstream of or within neuronal action potential and sleep. Predicted to be part of voltage-gated sodium channel complex. Predicted to be active in neuron projection. Is expressed in brain. Human ortholog(s) of this gene implicated in schizophrenia. Orthologous to human CACNA1I (calcium voltage-gated channel subunit alpha1 I). [provided by Alliance of Genome Resources, Apr 2022]
