In the course of retinoic acid-induced cell differentiation, formation of the complex between NPM1 (nucleophosmin) and TFAP2A (AP-2 alpha) homodimer, bound to the AP-2 alpha response element in the promoter of the MYBL2 (b-Myb) gene, represses transcription of the transcription factor MYBL2. Transcriptional repression probably involves NPM1-mediated recruitment of histone deacetylases HDAC1 and HDAC2 to the MYBL2 gene promoter (Liu et al. 2007). MYBL2 is involved in promotion of cellular proliferation (Saville and Watson 1998).
