PMPCA Substrate recognition and binding subunit of the essential mitochondrial processing protease (MPP), which is required for maturation of the majority of mitochondrial precursor proteins. Most MPP cleavage sites follow an arginine at position -2. Belongs to the peptidase M16 family. Ubiquitously expressed with highest expression in fetal tissues and adult brain, cerebellum and cerebellar vermis. 2 alternatively spliced human isoforms have been reported. Note: This description may include information from UniProtKB.
