英文摘要
This subproject is one of many research subprojects utilizing the resources provided by a Center grant funded by NIH/NCRR. The subproject and investigator (PI) may have received primary funding from another NIH source, and thus could be represented in other CRISP entries. The institution listed is for the Center, which is not necessarily the institution for the investigator. Driving Biological Project 2: Proteolytic Regulation of HIF-lalpha: An Ancient Protease Pathway Regulates the Von Hippel-Lindau Angiogenesis Network Patients with von Hippel-Lindau syndrome present with highly vascularized tumors of the CNS and the eye, because of a pro-angiogenic defect in the proteasome pathway. The von Hippel-Lindau protein is part of an E3 ubiquitin-protein ligase complex. This complex targets hypoxia-inducible factor (HIF)-1alpha for degradation. Our computational analysis of the Japanese pufferfish (Fugu rubripes) reveals an ancient fusion protein comprised of the von Hippel-Lindau protein, and two proteases, methionine aminopeptidase-2, and a LON-like protease. We plan to test the Rosetta stone hypothesis, namely that these three proteins are linked in a proteolytic network involved in regulating HIF-lalpha. Our work will include attempts to identify the substrates for each protease, and efforts to test their role in the HIF-lalpha pathway
