Gene: PYCR1 (pyrroline-5-carboxylate reductase 1) Homo sapiens
Symbol: PYCR1
Name: pyrroline-5-carboxylate reductase 1
Description: Exhibits identical protein binding activity and pyrroline-5-carboxylate reductase activity. Involved in several processes, including negative regulation of hydrogen peroxide-induced cell death; proline biosynthetic process; and regulation of mitochondrial membrane potential. Localizes to mitochondrion. Implicated in autosomal recessive cutis laxa type IIB and autosomal recessive cutis laxa type IIIB.
Type: protein-coding
RefSeq Status: REVIEWED
