Predicted to enable SNAP receptor activity and syntaxin binding activity. Predicted to be involved in exocytic insertion of neurotransmitter receptor to postsynaptic membrane; synaptic vesicle fusion to presynaptic active zone membrane; and synaptic vesicle priming. Predicted to act upstream of or within long-term synaptic potentiation. Is active in hippocampal mossy fiber to CA3 synapse and postsynaptic density. Orthologous to human SNAP47 (synaptosome associated protein 47). [provided by Alliance of Genome Resources, Apr 2022]
