PFAM accession number:PF01160
Interpro abstract (IPR006024):

Vertebrate endogenous opioid neuropeptides are released by post-translational proteolytic cleavage of precursor proteins. The precursors consist of the following components: a signal sequence that precedes a conserved region of about 50 residues; a variable-length region; and the sequence of the neuropeptide itself. Three types of precursor are known: preproenkephalin A (gene PENK), which is processed to produce 6 copies of Met-enkephalin, plus Leu-enkephalin; preproenkephalin B (gene PDYN), which is processed to produce neoendorphin, dynorphin, leumorphin, rimorphin and Leu-enkephalin; and prepronocipeptin (gene PNOC), whose processing produces nociceptin (orphanin FQ) and two other potential neuropeptides.

Sequence analysis reveals that the conserved N-terminal region of the precursors contains 6 cysteines, which are probably involved in disulphide bond formation. It is speculated that this region might be important for neuropeptide processing [ (PUBMED:8710928) ].
