Prkn Gene Summary [Mouse]
Enables ubiquitin protein ligase activity. Involved in several processes, including negative regulation of intrinsic apoptotic signaling pathway; positive regulation of dendrite extension; and positive regulation of protein metabolic process. Acts upstream of or within several processes, including catecholamine metabolic process; chemical synaptic transmission; and startle response. Located in mitochondrion; neuron projection; and nucleus. Part of protein-containing complex. Is active in dopaminergic synapse. Is expressed in several structures, including face; nervous system; pancreas; sensory organ; and skeleton. Used to study Parkinson's disease 2. Human ortholog(s) of this gene implicated in Parkinson's disease; Parkinson's disease 2; lung cancer; and ovarian cancer. Orthologous to human PRKN (parkin RBR E3 ubiquitin protein ligase).

Protein Domains
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 Prkn often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
