A transcriptional repressor NIR functions in the rRNA biogenesis of both the 40S and 60S subunits.
Aurora B (显示 AURKB 抗体) interacts with NIR-p53 (显示 TP53 抗体), leading to p53 (显示 TP53 抗体) phosphorylation in its DNA-binding domain and subsequent functional suppression.
Upon recruitment by p53 (显示 TP53 抗体), NIR represses transcription of both p53 (显示 TP53 抗体)-dependent reporters and endogenous target genes
Data define Nir as a key regulator of skin development.
results show that NIR cooperate with p53 (显示 TP53 抗体) to impose checkpoint for the generation of mature B and T lymphocytes.
Histone modification by histone acetyltransferases (HAT) and histone deacetylases (HDAC) can control major aspects of transcriptional regulation. NOC2L represents a novel HDAC-independent inhibitor of histone acetyltransferase (INHAT) (Hublitz et al., 2005
