Key Points

This research investigates how human clearance systems are structured within various tissues and cell types to support different proteome compositions.
Analyzed different tissue types for their clearance mechanisms including the autophagy-lysosome pathway and ubiquitin-proteasome system.
Utilized statistical tests such as Kolmogorov-Smirnov and Mann-Whitney to interpret the data.
Identified distinct clearance mechanisms across tissues, indicating a layered architecture.
Found that tissue-enriched pathways play a significant role in proteome variation.

Implication

Exploratory study highlights how layered clearance systems support diverse protein compositions across tissues.
