    basic FUNCTION
  • putatively involved in the activation of nuclear genes specifying mitochondrial function
  • being necessary for the expression of the Adenovirus E4 gene
  • GABPB1, GABPB2, GAPBA controls a critical transcription regulatory module that is essential for maintenance and differentiation of hematopoietic stem/progenitor cells
    • CELLULAR PROCESS nucleotide, transcription, regulation
    PHYSIOLOGICAL PROCESS
    PATHWAY
    metabolism
    signaling
    a component
  • component with GABPA alpha2/beta2 of an heterotetramer nuclear respiratory factor 2
    • INTERACTION
    DNA interacting with purine rich repeats (GA repeats)
    RNA
    small molecule
    protein
  • GABPA
  • NRF2 (E4F1) regulating STK6
  • recognizing an important site for herpes virus type I activation
  • interacting with HCFC1, causing repression of transcriptional activity
  • binding to GAPBA (through a DNA binding domain that binds to N-terminal ankyrin-like repeats of GABPB1 and GABPB2)
  • PRKD2 is a functionally significant mediator of the effect of GABPA, GABPB1, GABPB2 on proliferation and apoptosis of BCR-ABL–expressing cells
  • SIRT7 is a dynamic nuclear regulator of mitochondrial function through its impact on GABPB1 function
