    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

    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
  • cell & other
