The regulation of autophagy in eukaryotic cells: do all roads pass through Atg1?

abstract：:The N-terminal amino acid of a protein is an essential determinant of ubiquitination and subsequent proteasomal degradation in the N-end rule pathway. Using para-chloroamphetamine (PCA), a specific inhibitor of the arginylation branch of the pathway (Arg/N-end rule pathway), we identified that blocking the Arg/N-end r...

abstract：:Macroautophagy/autophagy involves the formation of an autophagosome, a double-membrane vesicle that delivers sequestered cytoplasmic cargo to lysosomes for degradation and recycling. Closely related, endocytosis mediates the sorting and transport of cargo throughout the cell, and both processes are important for cellu...
