Prrt2 Gene Summary [Rat]
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).

Protein Domains
A protein domain is a distinct structural or functional region within a protein that can evolve, function, and exist independently of the rest of the protein chain. These domains in rat Prrt2 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
