Enables mRNA 5'-UTR binding activity; pre-mRNA intronic binding activity; and translation regulator activity. Involved in Group I intron splicing; mitochondrial mRNA processing; and positive regulation of mitochondrial translation. Located in mitochondrial inner membrane and mitochondrial matrix.
SGD Description
Mitochondrial inner membrane protein; binds to the 5' UTR of the COX3 mRNA to activate its translation together with Pet122p and Pet494p; also binds to the COX1 Group I intron AI5 beta to facilitate exon ligation during splicing; also stimulates efficient synthesis of Cox1p
