摘要: Receptor-interacting protein 140 (RIP140) is a wide-spectrum coregulator for hormonal regulation of gene expression, but its activity in development/stem cell differentiation unknown. Here, we identify RIP140 as an immediate retinoic acid (RA)-induced dual-function chaperone LSD1 (lysine-specific demethylase 1). protects LSD1's catalytic domain and antagonizes Jade-2-mediated ubiquitination degradation. In RA-induced neuronal differentiation, the increased RIP140/LSD1 complex recruited by RA-elevated Pit-1 to specifically reduce H3K4me2 modification on Pax6 promoter, thereby repressing RA-induction Pax6. This study reveals new repressive mechanism that modulates abundance, enzyme quality, recruitment histone modifier regulator Pax6, which provides homeostatic control RA induction differentiation.
