Together, these data point to an important role for Tom1, Ubc4 and Ubc5 in normal physiology and prompt the authors to refer to this pathway as ERISQ, for excess ribosomal protein quality control.
Title: A conserved quality-control pathway that mediates degradation of unassembled ribosomal proteins.

Ubc4 and Ubc5 are 1) the primary E2s for Rsp5 in yeast and 2) act as monoubiquitinating E2s in RING E3-catalyzed pathways
Title: The essential Ubc4/Ubc5 function in yeast is HECT E3-dependent, and RING E3-dependent pathways require only monoubiquitin transfer by Ubc4.

Data demonstrated that excess histones associate with Rad53, and also identified Ubc4 and Ubc5, as well as Tom1 as enzymes involved in the ubiquitylation of excess histones.
Title: Histone levels are regulated by phosphorylation and ubiquitylation-dependent proteolysis.

These results show that Not4p functions as an E3 ligase by modulating Ubc4p/Ubc5p-mediated stress responses in vivo.
Title: Modulation of Ubc4p/Ubc5p-mediated stress responses by the RING-finger-dependent ubiquitin-protein ligase Not4p in Saccharomyces cerevisiae.

An Rsp5 dimer assembled on the RNA polymerase II (RNAP II) C-terminal domain; ubiquitylation sites bind Ubc5, which in turn binds Rsp5 to allow modification of RPB1 subunit of RNAP II.
Title: Communication between distant sites in RNA polymerase II through ubiquitylation factors and the polymerase CTD.
