| pubmed-article:16446359 | pubmed:abstractText | Ubiquitin E3 ligases are important cellular components for endoplasmic reticulum (ER)-associated degradation due to their role in substrate-specific ubiquitination, which is required for retrotranslocation (dislocation) of most unwanted proteins from the ER to the cytosol for proteasome degradation. However, our understanding of the molecular mechanisms of how E3 ligases confer substrate-specific recognition, and their role in substrate retrotranslocation is limited especially in mammalian cells. mK3 is a type III ER membrane protein encoded by murine gamma herpesvirus 68. As conferred by its N-terminal RING-CH domain, mK3 has E3 ubiquitin ligase activity. In its role as an immune evasion protein, mK3 specifically targets nascent major histocompatibility complex class I heavy chains (HC) for rapid degradation. The mechanism by which mK3 extracts HC from the ER membrane into the cytosol for proteasome-mediated degradation is unknown. Evidence is presented here that HC down-regulation by mK3 is dependent on the p97 AAA-ATPase. By contrast, the kK5 protein of Kaposi's sarcoma-associated herpesvirus is p97-independent despite the fact that it is highly homologous to mK3. mK3 protein was also found in physical association with Derlin1, an ER protein recently implicated in the retrotranslocation of HC by immune evasion protein US11, but not US2, of human cytomegalovirus. The mechanistic implications of these findings are discussed. | lld:pubmed |
