Summary
MAF1 (MAF1 negative regulator of RNA polymerase III, HGNC:24966) is a protein-coding gene on chromosome 8q24.3, encoding Repressor of RNA polymerase III transcription MAF1 homolog (Q9H063). Plays a role in the repression of RNA polymerase III-mediated transcription in response to changing nutritional, environmental and cellular stress conditions to balance the production of highly abundant tRNAs, 5S rRNA, and other small non-coding RNAs with cell growth and mainten….
This gene encodes a protein that is similar to Maf1, a Saccharomyces cerevisiae protein highly conserved in eukaryotic cells. Yeast Maf1 is a negative effector of RNA polymerase III (Pol III). It responds to changes in the cellular environment and represses pol III transcription. Biochemical studies identified the initiation factor TFIIIB as a target for Maf1-dependent repression.

Function. Plays a role in the repression of RNA polymerase III-mediated transcription in response to changing nutritional, environmental and cellular stress conditions to balance the production of highly abundant tRNAs, 5S rRNA, and other small non-coding RNAs with cell growth and maintenance. Also plays a key role in cell fate determination by promoting mesorderm induction and adipocyte differentiation. Mechanistically, associates with the RNA polymerase III clamp and thereby impairs its recruitment to the complex made of the promoter DNA, TBP and the initiation factor TFIIIB. When nutrients are available and mTOR kinase is active, MAF1 is hyperphosphorylated and RNA polymerase III is engaged in transcription. Stress-induced MAF1 dephosphorylation results in nuclear localization, increased targeting of gene-bound RNA polymerase III and a decrease in the transcriptional readout. Additionally, may also regulate RNA polymerase I and RNA polymerase II-dependent transcription through its ability to regulate expression of the central initiation factor TBP.
Subunit / interactions. Interacts with TFIIIB subunits BRF1 and BRF2. Interacts with Pol III subunit POLR3F. Interacts with TFIIIC subunit GTF3C1.
Subcellular location. Nucleus. Cytoplasm.
Post-translational modifications. Phosphorylated at Ser-60, Ser-68 and Ser-75; the major sites of phosphorylation. Nuclear accumulation correlates with a concomitant dephosphorylation. Phosphorylation may attenuate its RNA polymerase III-repressive function. Sumoylated with SUMO1 and SUMO2, mainly on Lys-35. Desumoylated by SENP1. SUMOylation promotes the ability of MAF1 to repress transcription and suppress colony formation.
Similarity. Belongs to the MAF1 family.

Enriched among interaction partners
Reactome pathways and GO biological processes over-represented among this gene’s 25 IntAct physical interaction partners (hypergeometric vs the genome-wide background, BH-FDR, gene-set size 15–500, ranked by fold). A functional readout of the neighbourhood — distinct from this gene’s own memberships above, and biased toward well-studied / hub proteins, so read it as themes rather than proof.
