Summary: Enables SH3 domain binding activity. Predicted to be involved in negative regulation of short-term synaptic potentiation; regulation of vesicle fusion; and synaptic vesicle fusion to presynaptic active zone membrane. Predicted to act upstream of or within neuromuscular process controlling posture. Located in neuron projection. 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).

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.

Status: VALIDATED

Description

Transcript Variant: This variant (2) contains an alternate 5' exon structure and lacks an alternate internal exon, compared to variant 1. This variant is represented as non-coding because it lacks a large portion of the coding region, including the translational start codon, found in variant 1.
