RPO41
L000001747, YFL036W
Mitochondrial RNA polymerase; single subunit enzyme similar to those of T3 and T7 bacteriophages; requires a specificity subunit encoded by MTF1 for promoter recognition; Mtf1p interacts with and stabilizes the Rpo41p-promoter complex, enhancing DNA bending and melting to facilitate pre-initiation open complex formation

Phenotypic Enhancement
A genetic interaction is inferred when mutation or overexpression of one gene results in enhancement of any phenotype (other than lethality/growth defect) associated with mutation or over expression of another gene.
Publication
Expression of the rDNA-encoded mitochondrial protein Tar1p is stringently controlled and responds differentially to mitochondrial respiratory demand and dysfunction.
The novel yeast protein Tar1p is encoded on the anti-sense strand of the multi-copy nuclear 25S rRNA gene, localizes to mitochondria, and partially suppresses the mitochondrial RNA polymerase mutant, rpo41-R129D. However, the function of Tar1p in mitochondria and how its expression is regulated are currently unknown. Here we report that Tar1p is subject to glucose repression and is up-regulated during ...
