MTF1 protein (Saccharomyces cerevisiae) - STRING interaction network
"MTF1" - Mitochondrial RNA polymerase specificity factor in Saccharomyces cerevisiae
Network nodes represent proteins
splice isoforms or post-translational modifications are collapsed, i.e. each node represents all the proteins produced by a single, protein-coding gene locus.
Node Color
colored nodes:
query proteins and first shell of interactors
white nodes:
second shell of interactors
Node Content
empty nodes:
proteins of unknown 3D structure
filled nodes:
some 3D structure is known or predicted
Edges represent protein-protein associations
associations are meant to be specific and meaningful, i.e. proteins jointly contribute to a shared function; this does not necessarily mean they are physically binding each other.
Known Interactions
from curated databases
experimentally determined
Predicted Interactions
gene neighborhood
gene fusions
gene co-occurrence
protein homology
Your Input:
Gene Fusion
MTF1Mitochondrial RNA polymerase specificity factor; has structural similarity to S-adenosylmethionine-dependent methyltransferases and functional similarity to bacterial sigma-factors; binding of Mtf1p to the core polymerase (Rpo41p)-promoter complex s /.../zes the binding and induces DNA bending; Mitochondrial transcription factor that confers selective promoter recognition on the core subunit of the yeast mitochondrial RNA polymerase. Interacts with DNA in a non-specific manner (341 aa)    
Predicted Functional Partners:
Mitochondrial RNA polymerase; single subunit enzyme similar to those of T3 and T7 bacteriophages; requires a specificity subunit encoded by MTF1 for promoter recognition; binding of Mtf1p to the Rpo41p-promoter complex stabilizes the binding and ind /.../NA bending; DNA-dependent RNA polymerase catalyzes the transcription of DNA into RNA using the four ribonucleoside triphosphates as substrates (1351 aa)
Delta(24)-sterol C-methyltransferase, converts zymosterol to fecosterol in the ergosterol biosynthetic pathway by methylating position C-24; localized to both lipid particles and mitochondrial outer membrane; Catalyzes the methyl transfer from S-adenosyl-methionine to the C-24 of zymosterol to form fecosterol (383 aa)
WD40 repeat-containing protein associated with the CCR4-NOT complex, interacts in a Ccr4p-dependent manner with Ssn2p; also interacts with Fis1p, Mdv1p and Dnm1p and plays a role in mitochondrial fission; Involved in mitochondrial fission. Has a partially redundant function to MDV1 in acting as an adapter protein, binding to FIS1 on the mitochondrial outer membrane and recruiting the dynamin-like GTPase DNM1 to form mitochondrial fission complexes. Plays a key role in determining the polarized localization of those DNM1 clusters that are not immediately involved in the mitochondrial fi [...] (643 aa)
Transcription factor IIIA (TFIIIA); essential DNA binding protein required for transcription of 5S rRNA by RNA polymerase III; not involved in transcription of other RNAP III genes; nine conserved zinc fingers; may also bind 5S rRNA; Interacts with the internal control region (ICR) of approximately 50 bases within the 5S RNA genes, is required for correct transcription of these genes by RNA polymerase III. Also binds the transcribed 5S RNA’s (429 aa)
Protein of unknown function; may play a role in cell wall biosynthesis, mutants are hypersensitive to anti fungal, Papulacandin B; null mutants have increased plasmid loss; interacts with Pdr5p (725 aa)
ATP-dependent RNA helicase, component of the mitochondrial degradosome along with the RNase Dss1p; the degradosome associates with the ribosome and mediates RNA turnover; also required during splicing of the COX1 AI5_beta intron; Required for intron-independent turnover and processing of mitochondrial RNA. It is a key control element in nuclear- mitochondrial interactions (737 aa)
DEAD-box protein required for efficient splicing of mitochondrial Group I and II introns; non-polar RNA helicase that also facilities strand annealing; ATP-dependent RNA helicase required for mitochondrial splicing of group I and II introns. Specifically involved in the ATP-dependent splicing of the bl1 intron of COB. Also required for efficient mitochondrial translation (664 aa)
Mitochondrial DNA-binding protein involved in mitochondrial DNA replication and recombination, member of HMG1 DNA-binding protein family; activity may be regulated by protein kinase A phosphorylation; Specific binding to the autonomously replicating sequence 1 (ARS1). Interaction with regulatory regions- probably involved in compacting the mitochondrial genome. It might play a positive role in gene expression and replication (183 aa)
Mitochondrial matrix protein that interacts with an N-terminal region of mitochondrial RNA polymerase (Rpo41p) and couples RNA processing and translation to transcription; Required for the processing and/or for the stability of the CYTB and COX1 intron-containing pre-mRNAs and of the ATP6 transcript. Could be a stem-loop RNA-binding protein that plays a role in determining RNA stability (440 aa)
Tetradecameric mitochondrial chaperonin required for ATP-dependent folding of precursor polypeptides and complex assembly; prevents aggregation and mediates protein refolding after heat shock; role in mtDNA transmission; phosphorylated; May participate in assembly and/or disassembly of proteins imported into the mitochondrion. HSP60 are ATPases and have affinity for unfolded proteins (572 aa)
