2.A.9.1.3
Cytochrome c oxidase assembly protein 18, COX18 of 333 aas and 4 TMSs. Acts transiently as a membrane insertase within the subunit 2 module of Cytochrome oxidase (Bourens and Barrientos 2017). Plays a central role in the translocation and export of the C-terminal part of the COX2 protein into the mitochondrial intermembrane space (Gaisne and Bonnefoy 2006).
