    text
  • predominantly nucleolar
  • shuttling between the nucleus and cytoplasm
  • nuclear import may be mediated by KPNA2, while export appears to depend partially on XPO1/CRM1
  • when rRNA transcription was suppressed by nucleolar stress, MYBBP1A translocated to the nucleoplasm and facilitated TP53-EP300 interaction to enhance TP53 acetylation
  • basic FUNCTION
  • may activate or repress transcription via interactions with sequence specific DNA-binding proteins
  • repressing JUN, MYB and PPARGC1A
  • stimulating transcription by AHR
  • may function to regulate cell type specific genes
  • novel substrate of AURKB and may be involved in mitosis (Perrera 2010)
  • CELLULAR PROCESS nucleotide, transcription, regulation
