Predicted to enable calcium-dependent phospholipid binding activity and phosphatidylserine binding activity. Predicted to be involved in cellular response to calcium ion and positive regulation of dendrite extension. Predicted to be located in several cellular components, including axon; clathrin-coated endocytic vesicle; and dendrite. Predicted to be active in plasma membrane. Orthologous to human CPNE6 (copine 6). [provided by Alliance of Genome Resources, Apr 2022]
