Short name: Synaptophysin/porin

Family relationships

  • Synaptophysin/synaptoporin (IPR001285)


Synaptophysin and synaptoporin are related glycoproteins: they are the major integral membrane proteins of a certain class of small neurosecretory vesicles, although they may also be found in vesicles of various non-endocrine cells [PMID: 3123215, PMID: 2492017]. The polypeptide chain spans the membrane four times and possibly acts as an ion or solute channel.
