RA Costanzo M.C., Fox T.D.;
RL Submitted (SEP-1997) to the EMBL/GenBank/DDBJ databases.
CC -!- FUNCTION: Required for expression of the mitochondrial gene for
CC cytochrome c oxidase subunit 3 (COX3). PET122 seems to work by directly
CC interacting with the small ribosomal subunit to promote translation
CC initiation on the COX3 mRNA (By similarity). {ECO:0000250}.
CC -!- SUBCELLULAR LOCATION: Mitochondrion inner membrane {ECO:0000250};
CC Peripheral membrane protein {ECO:0000250}.
