TrxG proteins and complexes that affect chromatin structure. (Top panel) TrxG proteins and protein complexes that modify histones. Complexes are shown, along with the histone modification(s) they catalyze. Proteins in green are designated TrxG proteins because mutants have TrxG phenotypes. All other subunits shown were identified as biochemical components of the complexes. (Bottom panel) TrxG proteins and protein complexes involved in chromatin remodeling. Proteins identified as products of genes whose mutants have TrxG phenotypes or that act as suppressors of Pc are in green. Pb, Bap170, and Sayp (blue) are present in PBAP, but not in BAP. All subunits shown in gray are present in both BAP and PBAP.
