Hrd3KR is fully integrated into the HRD-ligase. (A) Microsomes prepared from ∆hrd3 cells expressing plasmid-encoded HA-Hrd3 or HA-Hrd3KR were solubilized with NP40, and the Hrd3 variants were precipitated with anti-HA antibodies under nondenaturing conditions. The bound proteins were analyzed by SDS–PAGE and immunoblotting using the indicated antibodies. (B) HA-tagged Hrd3 variants were precipitated from lysates of yeast cells expressing HA-Hrd3 or HA-Hrd3KR and containing plasmids encoding Hrd3 or Hrd3KR under nondenaturing conditions. The precipitates were analyzed by immunoblotting with the given antibodies. (C) Plasmid-borne Hrd3 or Hrd3KR were expressed in ∆hrd3 Der1-Myc (left) or ∆hrd3 Hrd1-HA (right) cells. Der1-Myc and Hrd1-HA were then purified from solubilized microsomal preparations and the precipitates analyzed by immunoblotting with the indicated antibodies.
