Protein: Mitochondrial RNA-splicing protein MRS3 (P10566)
Organism: Saccharomyces cerevisiae (strain ATCC 204508 / S288c) (Baker's yeast)
Function: MRS3 suppresses a mitochondrial splice defect in the first intron of the COB gene. It may act as a carrier, exerting its suppressor activity via modulation of solute concentrations in the mitochondrion (possibly of cations).
Subcellular location: Mitochondrion inner membrane; Multi-pass membrane protein.
