Protein Name:
Mitochondrial-processing peptidase subunit beta
|
UniprotKB/SwissProt ID: Q9CXT8 (Q9CXT8)
Gene Name:
Pmpcb
Organism: Mus musculus (Mouse)
Function: Catalytic subunit of the essential mitochondrial processing protease (MPP), which cleaves the mitochondrial sequence off newly imported precursors proteins (By similarity). Preferentially, cleaves after an arginine at position P2 (By similarity). Required for PINK1 turnover by coupling PINK1 mitochondrial import and cleavage, which results in subsequent PINK1 proteolysis (By similarity)
