HEK293T cell degradome (pulse chase) analysis upon 12h Torin1 treatment. Related to Supplementary Table 3 from An et al (2020)


ABSTRACT: HEK293T Azidohomoalanine (AHA) Pulse Chase (degradome) experiment, were cells from various genetic background (WT, ATG7-/-, RB1CC1-/-) are treated or not with Torin1 for 12h. Samples are Biotin-click, and streptavidin enriched.

Nature 20200701 7815


Mammalian cells reorganize their proteomes in response to nutrient stress through translational suppression and degradative mechanisms using the proteasome and autophagy systems<sup>1,2</sup>. Ribosomes are central targets of this response, as they are responsible for translation and subject to lysosomal turnover during nutrient stress<sup>3-5</sup>. The abundance of ribosomal (r)-proteins (around 6% of the proteome; 10<sup>7</sup> copies per cell)<sup>6,7</sup> and their high arginine and lysin  ...[more]
