Proline-rich transmembrane protein 2 (Prrt2)

As a part of the outer core of AMPAR complicated, may be involved in synaptic transmission in the central nervous system. In hippocampal neurons, in presynaptic terminals, plays an important part in the final steps of neurotransmitter release, possibly by regulating Ca(2+)-sensing (PubMed:27052163).

In the cerebellum, may inhibit SNARE complex formation and downregulate short-term facilitation (PubMed:29056747). .
