Figure Legend Snippet: (A-B) Immunoblots for histone H2BK123ub1 and/or histone H3K4 methylation (mono, me1; di, me2; tri, me3) in extracts prepared from A) strains lacking Rad6, Bre1 or Lge1 and B) strains lacking Rad6, Bre1 or Lge1 in the background of ubp8Δubp10Δ double deletion mutant. Ponceau S staining and histone H3 levels served as loading controls. Histone H2BK123ub1 was detected using anti-H2B or anti-H2BK120 ubiquityl antibody. Molecular weights of the protein standards used as size markers (kDa) are indicated.
Techniques Used: Western Blot, Methylation, Mutagenesis, Staining

Figure Legend Snippet: (A) The steady-state levels of ubiquitination of a protein in vivo are maintained by the actions of ‘writer’ E2 ubiquitin-conjugating enzymes and E3 ubiquitin ligases and ‘eraser’ DUBs. (B) In yeast S. cerevisiae , the in vivo steady-state levels of H2BK123ub1 in a nucleosome are maintained by the ‘writer’ complex comprised of Rad6 (E2), Bre1 (E3) and accessory/adapter protein Lge1, and two ‘eraser’ DUBs, Ubp10 and the SAGA complex-associated Ubp8. IDR, intrinsically disordered region; cc, coiled-coil domain. (C) In the ubp8Δubp10Δ double null mutant strain, H2BK123ub1 accumulates due to ubiquitin addition and absence of deubiquitination. (D) High levels of H2BK123ub1 are not observed in the ubp8Δubp10Δ mutant strain when either the IDR or coiled-coil domain of Lge1 or the C-terminal acidic tail of Rad6 are deleted. Thus, the absence of relevant DUBs revealed the roles for various regions or domains of proteins involved in the ubiquitin-conjugation step. (E) Residues of the H2B C-terminal helix (Cα) impact the activity of the E2-E3 complex and the DUBs by influencing their access to substrate K123 or its ubiquitin conjugated form, respectively. Aspartate substitution at residue 120 in H2B Cα inhibits the Rad6-Bre1-Lge1-mediated monoubiquitination of H2BK123 in both WT and ubp8Δubp10Δ strains. In contrast, arginine substitution at position 120 in H2B Cα promotes removal of the conjugated ubiquitin by Ubp8 and Ubp10, as evidenced by the reduced H2BK123ub1 in the H2BA120R mutation in a strain expressing these two DUBs and not in their absence. Thus, the use of the DUB deletion strain informed on the dynamics of deubiquitination in addition to the ubiquitin conjugation.

Two lysine residues (H2BK120 and H2BK116) near G76 of ubiquitin are shown. H2BS112, whose GlcNAcylation stimulates H2BK120 ubiquitination, is also shown. c , Proposed mechanistic model. The wild-type Bre1 complex can bind to the nucleosome in two orientations, but H2BK120 ubiquitination occurs only when Bre1A binds to the acidic patch, as RING A , but not RING B , can recruit Rad6A and ubiquitin. Bre1B with G974T B -A978T B double substitution can recruit Rad6A and ubiquitin; thus, H2BK120 ubiquitination occurs in both binding modes.
