Predicted to enable calcium ion binding activity; metal ion transmembrane transporter activity; and mono-ADP-D-ribose binding activity. Involved in several processes, including calcium ion import across plasma membrane; estrous cycle; and positive regulation of insulin secretion. Located in neuron projection; neuronal cell body; and plasma membrane. Biomarker of transient cerebral ischemia. Orthologous to human TRPM2 (transient receptor potential cation channel subfamily M member 2). [provided by Alliance of Genome Resources, Apr 2022]
