Protein
Mitochondrial inner membrane protein OXA1
Organism
Saccharomyces cerevisiae (strain ATCC 204508 / S288c)
Function
Mitochondrial inner membrane insertase that mediates the insertion of both mitochondrion-encoded precursors and nuclear-encoded proteins from the matrix into the inner membrane. Links mitoribosomes with the inner membrane (PubMed:22904327). Forms pores capable of accommodating translocating protein segments (PubMed:22829595). Essential for the activity and assembly of cytochrome c oxidase (PubMed:22904327). Plays a central role in the translocation and export of the N-terminal part of the COX2 protein into the mitochondrial intermembrane space.
Similarity
Belongs to the OXA1/ALB3/YidC family.
