In mammalian cells, p62 is a target for CK2: its specific phosphorylation promotes selective autophagic turnover of polyubiquitinated cargo proteins.
Autophagy is a degradation pathway under ER stress conditions that is responsible for the turnover of intracellular cargo via lysosomal degradation (3).
Lysosomes are major cellular degradative organelles, involved in turnover of molecular cargo from both autophagic and endocytic pathways, and in AD, disturbed lysosomal degradation is presumed to be of key importance in aberrant AV turnover.
Although all studies agree that the observed phenomena relate to an impaired turnover of endosomal/autophagic cargo, whether lysosomal degradation per se or their fusion capacity is compromised, remains debated.
Also, when compared with CT cybrids, sPD cybrids showed increased basal levels of the autophagic substrate p62 which were not potentiated after lysosomal inhibition, demonstrating an impaired lysosomal turnover of protein cargo via autophagy in these cells (Fig. 10A and B).
The ESCRT machinery plays a fundamental role in the turnover of membrane bound cargo and functions to terminate receptor signaling in multiple contexts [5].
However, the rapid turnover observed for many PM proteins following exposure to heat stress seems wholly consistent with endocytic downregulation and could not be explained by the turnover of newly synthesized cargo via Golgi-to-endosome trafficking.
Valencia and Bilbau seaports needs to reduce fixed assets and the amount of labour by 15.25 % and 31.66 % respectively, and increase ships handled by 69.86 % and 8.94 %, while maintaining the same level of turnover and cargo throughput.
Sines seaport needs to reduce fixed assets by 60.81 %, the amount of labour by 34.91 % and increase ship handled by 480.61 %, while maintaining the same level of turnover and cargo throughput.
