Predicted to enable GTPase activity and calcium ion binding activity. Involved in T-helper 1 cell differentiation and positive regulation of JNK cascade. Predicted to be located in Golgi membrane; plasma membrane; and vesicle. Predicted to be active in several cellular components, including Weibel-Palade body; immunological synapse; and trans-Golgi network membrane. Is expressed in several structures, including alimentary system; bladder; cerebellum; male reproductive gland or organ; and trigeminal nerve. Orthologous to human CRACR2A (calcium release activated channel regulator 2A). [provided by Alliance of Genome Resources, Apr 2022]
