Enables low voltage-gated calcium channel activity. Involved in several processes, including artery smooth muscle contraction; calcium ion transport; and cellular response to dexamethasone stimulus. Located in several cellular components, including dendrite; neuronal cell body; and perinuclear region of cytoplasm. Human ortholog(s) of this gene implicated in cerebellar ataxia type 42. Orthologous to human CACNA1G (calcium voltage-gated channel subunit alpha1 G). [provided by Alliance of Genome Resources, Apr 2022]
