Predicted to enable calcium ion binding activity. Predicted to be involved in regulation of long-term synaptic potentiation and regulation of presynaptic cytosolic calcium ion concentration. Predicted to be located in extracellular region and transport vesicle membrane. Predicted to be active in several cellular components, including cytosol; dendrite; and terminal bouton. Orthologous to human SCGN (secretagogin, EF-hand calcium binding protein). [provided by Alliance of Genome Resources, Apr 2022]
