Summary: Enables syntaxin-1 binding activity. Involved in negative regulation of short-term synaptic potentiation; regulation of vesicle fusion; and synaptic vesicle fusion to presynaptic active zone membrane. Located in axon terminus; plasma membrane; and synaptic vesicle. Is active in glutamatergic synapse and presynaptic membrane. Is expressed in brain and spinal cord. Used to study episodic kinesigenic dyskinesia 1. Human ortholog(s) of this gene implicated in benign familial infantile seizures 2 and episodic kinesigenic dyskinesia 1. Orthologous to human PRRT2 (proline rich transmembrane protein 2). [provided by Alliance of Genome Resources, Nov 2024]

Study describes the phenotype of KO mice for PRRT2 and shows that its loss-of-function recapitulates the human phenotype in terms of episodic disturbances in motor coordination and paroxysmal dyskinesias, suggesting that PRRT2 plays a critical role in the development of cortical connectivity and functional stability of neuronal networks.

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
