Fluorescence-based imaging of autophagy progression by human WIPI protein detection.
Tübingen, Germany. In Methods, Mar 2015
The specific autophagosomal localization of both WIPI1 and WIPI2 (refered to as WIPI puncta) has been employed to assess autophagy using fluorescence microscopy methods, such as confocal and live-cell video microscopy and was extended for automated high-throughput image acquisition and analyses procedures.
WIPI proteins: essential PtdIns3P effectors at the nascent autophagosome.
Tübingen, Germany. In J Cell Sci, Feb 2015
Members of the human WD-repeat protein interacting with phosphoinositides (WIPI) family play an important role in recognizing and decoding the PtdIns3P signal at the nascent autophagosome, and hence function as autophagy-specific PtdIns3P-binding effectors, similar to their ancestral yeast Atg18 homolog.
WIPI β-propellers in autophagy-related diseases and longevity.
Tübingen, Germany. In Biochem Soc Trans, 2013
In the present article, we discuss the role of human WIPIs in autophagy, and the identification of evolutionarily conserved amino acids of WIPI-1 that confer PtdIns(3)P binding downstream of mTORC1 inhibition.
Autophagosome formation and molecular mechanism of autophagy.
Japan. In Antioxid Redox Signal, 2011
Among the proteins and multimolecular complexes that contribute to autophagosome formation are the PI(3)-binding proteins, the PI3-phosphatases, the Rab proteins, the Atg1/ULK1 protein-kinase complex, the Atg9•Atg2-Atg18 complex, the Vps34-Atg6/beclin1 class III PI3-kinase complex, and the Atg12 and Atg8/LC3 conjugation systems.
Tokyo, Japan. In Microbiol Immunol, 2011
The "core" autophagy-related (Atg) complexes in mammals are ULK1 protein kinase, Atg9-WIPI-1 and Vps34-beclin1 class III PI3-kinase complexes, and the Atg12 and LC3 conjugation systems.
