Bcl-2-associated transcription factor 1 (BCLAF1)

Bcl-2-associated transcription factor 1 (BCLAF1) is a multifunctional nuclear protein originally identified as a pro-apoptotic transcriptional repressor that interacts with members of the BCL2 family[1][3][2][4][7]. Overexpression can induce apoptosis, which can be suppressed by anti-apoptotic BCL2 proteins. BCLAF1 is involved in diverse cellular processes, including transcriptional repression, mRNA splicing, and coordination of DNA damage response. It is essential for genomic stability, acting as part of splicing and gene regulatory complexes required for DNA repair protein expression. BCLAF1 is also important in development (notably in lung and smooth muscle lineage organization), immune system homeostasis, and T-cell activation. Dysregulation has been implicated in tumorigenesis, hematologic malignancy, muscular dystrophy, and cellular senescence[1][4][3]. There are currently no approved drugs directly targeting BCLAF1, but it is considered an emerging target of therapeutic interest in cancer biology.
