靶點詳情

  • 功能：
    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. Plays also 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.

    1. can act as a transcriptional activator for PTEN, which is important for MAF1's tumor-suppressor function PMID: 26910647
    2. Repression of Pol III recruitment and transcription are tightly linked to MAF1, which selectively localizes at Pol III loci, even under serum-replete conditions, and increasingly targets transcribing Pol III in response to serum starvation PMID: 26941251
    3. These results reveal a novel mechanism by which MAF1 and Pol III regulate the activity of the CDKN1A-encoding gene transcribed by Pol II. PMID: 26067234
    4. novel role for Maf1 in suppressing both lipid biogenesis and tumor formation; Maf1 elicits these biological responses through its ability to repress genes that that synthesize lipids and regulate biosynthetic capacity. PMID: 25502566
    5. Studies on Maf1 regulation up until now have focused on posttranslational mechanisms, notably phosphorylation, which controls Maf1 localization (in yeast) and its interaction with the polymerase (in yeast and humans) PMID: 25568945
    6. SUMOylation has a role in controlling Maf1 and RNA pol III-mediated transcription PMID: 23673667
    7. Recovery of RNA polymerase III transcription from the glycerol-repressed state: revisiting the role of protein kinase CK2 in Maf1 phosphoregulation. PMID: 22810236
    8. The TOR pathway controls another aspect of Pol III transcription that is closely linked to MAF1, as it depends on the presence of MAF1. PMID: 21428925
    9. an important role of CK2-mediated Maf1 phosphorylation in triggering Pol III activation. PMID: 21383183
    10. Data relate Pol III transcription inhibition to Maf1 structural changes. PMID: 20817737
    11. Maf1, a repressor that binds and inhibits pol III, is phosphorylated in a mTOR-dependent manner both in vitro and in vivo at serine 75, a site that contributes to its function as a transcriptional inhibitor. PMID: 20543138
    12. mTOR inhibition led to an increase in the occupancy of Maf1 on a set of Pol III-dependent genes, with concomitant reduction in the binding of Pol III and Brf1 PMID: 20233713
    13. Maf1 can be co-immunoprecipitated with pol III and associates in vitro with two pol III subunits, the largest subunit RPC1 and the alpha-like subunit RPAC2. Maf1 represses pol III transcription in vitro and in vivo. PMID: 17205138
    14. The human Maf1 protein negatively regulates transcription by all three nuclear Pols. Changes in Maf1 expression affect Pol I- and Pol III-dependent transcription in human glioblastoma lines. PMID: 17499043
    15. represses RNA polymerase III transcription via TFIIIB, specifically through the TFIIB family members Brf1 and Brf2 PMID: 17505538
