WebDec 1, 2015 · Crosstalk between a reader and a catalytic domain can occur when both are encoded in the same polypeptide or are part of two distinct polypeptides within the same protein complex. Multivalent engagement of histone modifications can occur when on the same histone (cis), on adjacent histones within the same nucleosome (intranucleosomal) … WebSimilarly, we show that the association of the Sin3A complex with pericentromeric heterochromatin is also sensitive to TSA (Fig. (Fig.7B) 7B) and that RbAp46 binds preferentially to hypoacetylated histones, presumably H3, in vitro (Fig. (Fig.7A). 7A). Thus, interaction with hypoacetylated histones seems to be a conserved function among WD-40 ...

Furthermore, this shows that plant homeodomain proteins play a yet unexplored role in recruiting chromatin remodeling complexes to acetylated histones.
WebHistone acetylation marks are written by histone acetyltransferases (HATs) and read by bromodomains (BrDs), and less commonly by other protein modules. These proteins regulate many transcription-mediated biological processes, and their aberrant activities are correlated with several human diseases. WebOct 16, 2015 · Readers of these marks contain protein domains that allow their recruitment to chromatin. Interestingly, writers often contain domains which can read chromatin marks, allowing the reinforcement of modifications through a positive feedback loop or inhibition of their activity by other modifications.
