Pycr1 Gene Summary [Rat]
Predicted to enable identical protein binding activity and pyrroline-5-carboxylate reductase activity. Predicted to be involved in several processes, including L-proline biosynthetic process; negative regulation of oxidative stress-induced neuron intrinsic apoptotic signaling pathway; and regulation of mitochondrial membrane potential. Predicted to be located in mitochondrion. Human ortholog(s) of this gene implicated in autosomal recessive cutis laxa type IIB and autosomal recessive cutis laxa type IIIB. Orthologous to human PYCR1 (pyrroline-5-carboxylate reductase 1). [provided by Alliance of Genome Resources, Jul 2025]

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 rat Pycr1 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
