SUBCELLULAR LOCALIZATION	plasma membrane
text	predominantly localizes to the pre-synaptic terminals and is believed to regulate neurotransmitter release

basic FUNCTION	plays a role in epilepsy
	wild-type PRRT2 (PRRT2wt) had an inhibitory effect in proliferation, consistent with the low expression level of PRRT2 in cancer versus normal prostate samples
	selectively blocks the trans SNARE complex assembly and thus negatively regulates synaptic vesicle priming

INTERACTION

DNA

RNA

small molecule

protein	interacts with synaptosomal-associated protein 25 kDa (SNAP25), and plays a role in neurotransmitter release from synaptic vesicles
	interact with SNAP25, a component of the molecular machinery involved in the release of neurotransmitters at the presynaptic membrane
	is an important negative modulator of SCN8A and SCN2 channels
