..The interaction matrix of Arabidopsis TAFs is largely consistent with the three-lobed topological map for yeast TFIID, which suggests that the structure and composition of TFIID have been highly conserved among eukaryotes. ..

..These data suggest that the E3 ubiquitin ligase AtCHIP may function upstream of PP2A in stress-responsive signal transduction pathways under conditions of low temperature or in the dark. ..
