Predicted to enable several functions, including beta-tubulin binding activity; phosphatidylserine binding activity; and ubiquitin protein ligase binding activity. Involved in negative regulation of cellular component organization and negative regulation of dopamine secretion. Located in several cellular components, including inhibitory synapse; presynaptic active zone membrane; and synaptic vesicle. Is active in Schaffer collateral - CA1 synapse and postsynapse. Is integral component of presynaptic active zone membrane and integral component of synaptic vesicle membrane. Orthologous to human SYT11 (synaptotagmin 11).
