    basic FUNCTION
  • death promoting transcriptional repressor
  • is required for proper spatial and temporal organization of smooth muscle lineage during the saccular stage of lung development
  • is essential for peripheral T-cell homeostasis
  • inducing apoptosis upon overexpression
  • BCLAF1 has functions distinct from THRAP3 in regulating the subcellular distribution of mRNAs in human cells
  • RNA processing factors THRAP3 and BCLAF1 promote the DNA damage response through selective mRNA splicing and nuclear export
  • BCLAF1 is a novel positive regulator of HIF1A in the hypoxic microenvironment
    • CELLULAR PROCESS nucleotide, transcription, regulation

    INTERACTION
    DNA
    RNA
    small molecule
    protein
  • binding to emerin by two regions of emerin flanking its lamin-binding domain
  • interacting with BCL2
  • interacting with antiapoptotic members of Bcl2 protein family, thus preventing its nuclear localization
  • both THRAP3 and BCLAF1 are associated with the spliceosome, indicating their potential role in pre-mRNA splicing
  • CCDC80 overexpression resulted in BCLAF1 upregulation
  • 10 FXR1-interacting proteins including Bcl-2-associated transcription factor 1 (BCLAF1)
  • BCLAF1 is involved in tumorigenesis, and the responsiveness of BCLAF1 to NFKB1 may determine the effectiveness of therapeutic drugs
