Enables calcium channel activity and identical protein binding activity. Involved in calcium ion import across plasma membrane and response to calcium ion. Acts upstream of or within calcium ion transport and parathyroid hormone secretion. Part of calcium channel complex. Is expressed in alimentary system; central nervous system; metanephros; and sensory organ. Human ortholog(s) of this gene implicated in hyperparathyroidism. Orthologous to human TRPV6 (transient receptor potential cation channel subfamily V member 6). [provided by Alliance of Genome Resources, Apr 2022]
