Neurexophilin

Neurexophilin
PFAM accession number:PF06312
Interpro abstract (IPR026845):

This entry includes neurexophilin and NXPE proteins.

Neurexophilins form a family of related glycoproteins that are proteolytically processed after synthesis and bind to alpha-neurexins. The structure and characteristics of neurexophilins indicate that they function as neuropeptides that may signal via alpha-neurexins [(PUBMED:9570794)].

NXPE is a glycoprotein with unknown function.

This is a PFAM domain. For full annotation and more information, please see the PFAM entry Neurexophilin
