MTF1/YMR228W Summary Help

Standard Name MTF1
Systematic Name YMR228W
Feature Type ORF, Verified
Description Mitochondrial RNA polymerase specificity factor; has structural similarity to S-adenosylmethionine-dependent methyltransferases and functional similarity to bacterial sigma-factors; Mtf1p interacts with and stabilizes the Rpo41p-promoter complex, enhancing DNA bending and melting to facilitate pre-initiation open complex formation (1, 2, 3, 4, 5)
Name Description Mitochondrial Transcription Factor 6
