| dynorphin | <protein> Opiate peptide derived from the hypothalamic precursor pro dynorphin (that also contains the neoendorphin sequences). Contains the penta peptide leu enkephalin sequence. Its binding affinity is greater for the _ type than for the _ type opioid receptor. (18 Nov 1997) |

| dynorphin-converting endopeptidase | <enzyme> Enzyme from human cerebrospinal fluid; cleaves dynorphin a and b and neoendorphin at the arg(6)-arg(7) or arg(6)-lys(7) bonds Registry number: EC 3.4.21.- Synonym: dynorphin-neo-endorphin endopeptidase, dc-endopeptidase (26 Jun 1999) |
| dynorphins | <chemical> A class of opioid peptides including dynorphin a, dynorphin b, and smaller fragments of these peptides. Dynorphins prefer kappa-opioid receptors (receptors, opioid, kappa) and have been shown to play a role as central nervous system transmitters. Chemical name: Dynorphin (12 Dec 1998) |
Synonyms : Dynorphin, Dynorphin (1-17), Dynorphin A, Dynorphin A (1-17)
| dynorphin |
any of a family of opioid peptides found throughout the central and peripheral nervous systems; most are agonists at opioid receptor sites. Some are probably involved in pain regulation at the levels of the spinal cord and medulla and others may aid hypothalamic regulation of eating and drinking. See also endorphin and enkephalin.
