Abstrakt: | Aberrant endoplasmic reticulum (ER) and inner nuclear membrane (INM) proteins are destroyed through ER-associated degradation (ERAD) and INM-associated degradation (INMAD). We previously showed the Hrd1, Doa10, and Asi ERAD and INMAD ubiquitin ligases (E3s) in Saccharomyces cerevisiae confer resistance to hygromycin B, which distorts the ribosome decoding center. Here, we assessed the requirement of Ubc6 and Ubc7, the primary ERAD and INMAD ubiquitin-conjugating enzymes (E2s) for hygromycin B resistance. Loss of either E2 sensitized cells to hygromycin B, with UBC7 deletion having a greater impact, consistent with characterized roles for Ubc6 and Ubc7 in ER and INM protein quality control.
