basic FUNCTION
| acts as a membrane-bound chaperone necessary for cleavage of COX2 and for interaction of the mature protein with other subunits of cytochrome oxidase in a later step of the assembly process  |
|
control the coordinate assembly process to prevent potentially harmful redox reactions of unassembled or misassembled subunits  |
|
serves as a substrate-specific cofactor during proteolysis and modulates the initial interaction of nonassembled COX2 with the protease  |
|
required for efficient export of the COX2 C-tail  |
|
COX20 chaperone has important roles in leader peptide processing, C-tail export, and stabilization of COX2  |
