Dinorfine
Sign in to saveAlso known as dynorphins
Dynorphins (Dyn) are a class of opioid peptides that arise from the precursor protein prodynorphin. When prodynorphin is cleaved during processing by proprotein convertase 2 (PC2), multiple active peptides are released: dynorphin A, dynorphin B, and α/β-neoendorphin. Depolarization of a neuron containing prodynorphin stimulates PC2 processing, which occurs within synaptic vesicles in the presynaptic terminal. Occasionally, prodynorphin is not fully processed, leading to the release of big dynorphin, a 32-amino acid molecule consisting of both dynorphin A and dynorphin B.

Le dinorfine sono dei peptidi oppioidi endogeni che derivano dalla prodinorfina il cui produce la α-, la β-neoendorfina, la dinorfina A e la dinorfina B. Questa famiglia di peptidi endogeni è quella che mostra la maggiore affinità di legame per i recettori κ e la minore per i recettori μ e i δ.
