Protein Name:
Mitochondrial-processing peptidase subunit beta
|
UniprotKB/SwissProt ID: Q03346 (Q03346)
Gene Name:
Pmpcb
Organism: Rattus norvegicus (Rat)
Function: Catalytic subunit of the essential mitochondrial processing protease (MPP), which cleaves the mitochondrial sequence off newly imported precursors proteins (Probable) (PubMed:12433926). Preferentially, cleaves after an arginine at position P2 (PubMed:12433926). Required for PINK1 turnover by coupling PINK1 mitochondrial import and cleavage, which results in subsequent PINK1 proteolysis (PubMed:22354088)
