Predicted to enable metal ion binding activity; protein kinase binding activity; and voltage-gated calcium channel activity involved in regulation of presynaptic cytosolic calcium levels. Predicted to be involved in phosphatidylinositol-mediated signaling; regulation of exocytosis; and regulation of neuron projection development. Predicted to act upstream of or within positive regulation of synaptic transmission. Located in axon and dendrite. Is expressed in brain; dorsal root ganglion; and spinal cord. Orthologous to human NCS1 (neuronal calcium sensor 1). [provided by Alliance of Genome Resources, Apr 2022]
