GABPA directly activates DICER1 transcription by binding to the DICER1 promoter; mutation of the GABPA binding site in the DICER1 promoter diminished basal DICER1 promoter activity and abolished GABPA-stimulated promoter activity. GABPA depletion reduced DICER1 expression and increased cellular invasion in thyroid carcinoma cells, while forced DICER1 expression rescued the invasive phenotype of GABPA-depleted cells. |

GABPA directly activates TGFBR2 transcription (identified by RNA-seq and ChIP); GABPA and TGFBR2 phenocopy each other in clear cell renal cell carcinoma (ccRCC) cells, governing TGFβ signaling to suppress proliferation, invasion, and stemness. The oncometabolite L-2-hydroxyglutarate (L-2HG) silences GABPA expression by increasing GABPA gene methylation, thereby disrupting the GABPA–TGFβ axis. |

GABPA mediates regulation of BRAFV600E/MAPK signaling on TERT reactivation by selectively recruiting activated ERK to the mutant TERT promoter, where ERK phosphorylates Sp1, causing HDAC1 dissociation and active chromatin. Phosphorylated Sp1 further enhances GABPA binding to the mutant TERT promoter, establishing a synergistic activation loop. |

METTL23 physically interacts with GABPA (co-immunoprecipitation). Overexpression of METTL23 increased transcriptional activity at the THPO promoter (a GABPA target), while siRNA knockdown of METTL23 decreased expression of ATP5B (another GABPA target), establishing METTL23 as a co-regulator of GABPA transcriptional function. |

The GABPA cistrome in THP-1 monocytes (3822 loci) overlaps significantly with VDR binding sites; ~23% of persistent VDR binding sites co-localize with GABPA. About 40% of GABPA binding sites are at transcription start sites, including ~100 of 1,25(OH)2D3 target genes, indicating GABPA contributes to differential vitamin D receptor target gene regulation. |

GABPA remains bound to specific genomic sites during mitosis and cooperates with histone acetylation marks (H3K9/14Ac, H3K27Ac, H4K5Ac) to act as a mitotic bookmarking factor. Depletion of GABPA increases H4K5Ac levels at target gene regions and induces transcriptional activation in early G1, suggesting GABPA negatively regulates transcription during the M/G1 transition. |

Gain-of-function mutant p53 (R273H) co-localizes genomically with GABPA binding sites at bidirectional promoters enriched for closely spaced ETS motifs. GABPA shows increased binding signal with higher numbers of ETS motifs per promoter and prefers promoters with closely spaced inverted ETS motifs, in contrast to ETS1. |

GABPA induces miR-30e expression by stimulating DICER1 transcription; higher miR-30e levels consequently target P4HA2 for downregulation. This GABPA→DICER1→miR-30e→P4HA2 axis reduces collagen I and III formation (ECM deposition), lowers ECM stiffness, suppresses YAP1 nuclear translocation (mechanotransduction), and restrains bladder cancer aggressiveness in xenograft models. |
