| Research Abstract |
The present study investigated the cellular mechanism underlying the degradation of heme oxygenase(HO), an endoplasmic reticulum-anchored protein. High molecular weight ubiquitin conjugates were co-immunoprecipitated with HO from HEK293 cells after proteasome inhibition, and HO ubiquitination was confirmed in HEK293 cells overexpressing His-tagged HO and HA-tagged ubiquitin. HO specific ubiquitine-ligase was also identified using mass spectrometry.
