Description

Predicted to enable low voltage-gated calcium channel activity and voltage-gated sodium channel activity. Predicted to be involved in calcium ion import; membrane depolarization during action potential; and positive regulation of calcium ion-dependent exocytosis. Predicted to act upstream of or within calcium ion transmembrane transport. Predicted to be located in membrane. Predicted to be part of voltage-gated sodium channel complex. Predicted to be active in neuron projection. Is expressed in atrium and cardiac ventricle. Used to study congenital heart disease. Human ortholog(s) of this gene implicated in primary ciliary dyskinesia and type 2 diabetes mellitus. Orthologous to several human genes including CFAP74 (cilia and flagella associated protein 74).
