Proenkephalin B
Extracted from the Wikipedia article Prodynorphin.
Prodynorphin, also known as proenkephalin B, is an opioidpolypeptidehormone involved with chemical signal transduction and cell communication. The gene for prodynorphin is expressed in the endometrium and the striatum, and its gene map locus is 20pter-p12. Prodynorphin is a basic building-block of dynorphins, the chemical messengers in the brain that appear most heavily involved in the anticipation and experience of pain, stress responses, as well appetite and temperature regulation, as well as neoendorphins.
