Penk

Enables opioid peptide activity and opioid receptor binding activity. Involved in G protein-coupled opioid receptor signaling pathway; regulation of long-term synaptic depression; and transmission of nerve impulse. Acts upstream of or within several processes, including behavioral fear response; sensory perception of pain; and startle response. Predicted to be located in several cellular components, including cell body fiber; perikaryon; and symmetric synapse. Predicted to be active in several cellular components, including axon terminus; cytoplasmic vesicle lumen; and neuronal cell body. Is expressed in several structures, including alimentary system; brain; genitourinary system; integumental system; and sensory organ. Human ortholog(s) of this gene implicated in overactive bladder syndrome. Orthologous to human PENK (proenkephalin). [provided by Alliance of Genome Resources, Jul 2025]

A protein domain is a distinct structural or functional region within a protein that can evolve, function, and exist independently of the rest of the protein chain. These domains in mouse Penk often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
