Enables low voltage-gated calcium channel activity. Involved in several processes, including calcium ion import; positive regulation of cardiac muscle cell contraction; and primary alcohol biosynthetic process. Located in several cellular components, including dendrite; nucleus; and perikaryon. Biomarker of sciatic neuropathy. Human ortholog(s) of this gene implicated in childhood absence epilepsy and primary hyperaldosteronism. Orthologous to human CACNA1H (calcium voltage-gated channel subunit alpha1 H).
