Two group I mitochondrial introns in the cob-box and coxI genes require the same MRS1/PET157 nuclear gene product for splicing.

Current genetics - 1 Aug 1990

Abstract excerpt

We have studied the role of the product of the nuclear gene PET157 in mitochondrial pre-mRNA splicing. Cytoduction experiments show that a mitochondrial genome deleted for the three introns bI3, aI5 and aI6 is able to suppress the pet157-1 mutation: the strain recovers respiratory competency indicating that the product of the PET157 gene is only required for mitochondrial pre-mRNA splicing. Characterization of...
