| Research Abstract |
Transcription factor PU. 1 is a hematopoietic master regulator and essential for the development of myeloid and B-cell lineages. PU. 1 functions in concert with other transcription factors and cofactors. As we shown previously represented, PU. 1 interact with both p300/cbp, which function as a coactivator and HDAC, which function as a corepressor. In this study, to determine whether modification of PU. 1 is responsible for switching its association between coactivaor and corepressor, we examined whether acetylation regulates the physical and functional activities of PU. 1.We found that PU. 1 was acetylated in vivo and its repressor activity was reduced when the putative acetylation motif in ETS domain were mutated. Our data suggest that acetylation might regulate the biological functions in erythroid cells.
