CC -!- FUNCTION: Plays a role in the repression of RNA polymerase III-mediated
CC transcription in response to changing nutritional, environmental and
CC cellular stress conditions to balance the production of highly abundant
CC tRNAs, 5S rRNA, and other small non-coding RNAs with cell growth and
CC maintenance (By similarity). Also plays a key role in cell fate
CC determination by promoting mesorderm induction and adipocyte
CC differentiation (PubMed:30110641). Mechanistically, associates with the
CC RNA polymerase III clamp and thereby impairs its recruitment to the
CC complex made of the promoter DNA, TBP and the initiation factor TFIIIB.
CC When nutrients are available and mTOR kinase is active, MAF1 is
CC hyperphosphorylated and RNA polymerase III is engaged in transcription.
CC Stress-induced MAF1 dephosphorylation results in nuclear localization,
CC increased targeting of gene-bound RNA polymerase III and a decrease in
CC the transcriptional readout. Additionally, may also regulate RNA
CC polymerase I and RNA polymerase II-dependent transcription through its
CC ability to regulate expression of the central initiation factor TBP (By
CC similarity). {ECO:0000250|UniProtKB:Q9H063,
CC ECO:0000269|PubMed:30110641}.
CC -!- SUBUNIT: Interacts with TFIIIB subunits BRF1 and BRF2. Interacts with
CC Pol III subunit POLR3F. Interacts with TFIIIC subunit GTF3C1.
CC {ECO:0000250|UniProtKB:Q9H063}.
CC -!- SUBCELLULAR LOCATION: Nucleus {ECO:0000269|PubMed:20543138}. Cytoplasm
CC {ECO:0000250|UniProtKB:Q9H063}.
CC -!- PTM: Phosphorylated at Ser-60, Ser-68 and Ser-75; the major sites of
CC phosphorylation. Nuclear accumulation correlates with a concomitant
CC dephosphorylation. Phosphorylation may attenuate its RNA polymerase
CC III-repressive function (By similarity). {ECO:0000250}.
CC -!- PTM: Sumoylated with SUMO1 and SUMO2, mainly on Lys-35. Desumoylated by
CC SENP1. SUMOylation promotes the ability of MAF1 to repress
CC transcription and suppress colony formation (By similarity).
CC {ECO:0000250}.
CC -!- DISRUPTION PHENOTYPE: MAF1 deficient mice display a decreased metabolic
CC efficiency. Constitutive high levels of Pol III transcription reprogram
CC central metabolic pathways and waste metabolic energy through a futile
CC RNA cycle (PubMed:30429315, PubMed:25934505). MAF1 down-regulation also
CC alters the expression of genes involved in lipid and sugar metabolism
CC (PubMed:30110641). {ECO:0000269|PubMed:25934505,
CC ECO:0000269|PubMed:30110641, ECO:0000269|PubMed:30429315}.
CC -!- SIMILARITY: Belongs to the MAF1 family. {ECO:0000305}.
