PENK proenkephalin [ Homo sapiens (human) ]
Source: NCBI Gene (ID 5179)
Symbol: PENK
Full name: proenkephalin
Gene type: protein coding
RefSeq status: REVIEWED
Organism: Homo sapiens
Also known as: PE; PENK-A
Summary: This gene encodes a preproprotein that is proteolytically processed to generate multiple protein products. These products include the pentapeptide opioids Met-enkephalin and Leu-enkephalin, which are stored in synaptic vesicles, then released into the synapse where they bind to mu- and delta-opioid receptors to modulate the perception of pain. Other non-opioid cleavage products may function in distinct biological activities. [provided by RefSeq, Jul 2015]
