The N-terminal domain contains 6 conserved cysteines thought to be involved in disulfide bonding and\/or processing. Leu-enkephalins, which is a type of Proenkephalin-B, compete with and mimic the effects of opiate drugs. They play a role in a number of physiologic functions, including pain perception and responses to stress. Dynorphin peptides differentially regulate the kappa opioid receptor. Dynorphin A has a typical opiod activity, it is 700 times more potent than Leu-enkephalin.\u003c\/p\u003e\n\n\u003cp\u003eAlternate Names: ADCA; PENKB; SCA23; PDYN; Dynorphin B; Big Dyn\u003c\/p\u003e\n\n\u003cp\u003eDescription: Recombinant Human Proenkephalin-B is produced by our Mammalian expression system and the target gene encoding Asp21-Ala254 is expressed with a 6His tag at the C-terminus.\u003c\/p\u003e\n\n\u003cp\u003eAccession: P01213\u003c\/p\u003e\n\n\u003cp\u003eMolecular Weight: 27.3 KDa\u003c\/p\u003e\n\n\u003cp\u003eApparent Molecular Weight: 35 KDa, reducing conditions\u003c\/p\u003e\n\n\u003cp\u003eStorage Condition: Lyophilized protein should be stored at \u0026lt; -20°C, though stable at room temperature for 3 weeks.
