Enables calcium-dependent phospholipid binding activity; clathrin binding activity; and syntaxin binding activity. Predicted to be involved in cellular response to calcium ion; regulation of secretion by cell; and synaptic vesicle cycle. Predicted to be located in neuronal cell body; perinuclear region of cytoplasm; and proximal neuron projection. Predicted to be active in axon; plasma membrane; and secretory vesicle. Predicted to be integral component of neuronal dense core vesicle membrane. Orthologous to human SYT5 (synaptotagmin 5). [provided by Alliance of Genome Resources, Apr 2022]
