An in vivo resource of age-regulated C. elegans intestinal secretory-pathway proteins highlights secreted enzymes associated with lifespan regulation.
Secreted proteins are essential to modulate homeostasis in the extracellular space and facilitate communication to distal cells or tissues. Yet, the identity and functional importance of extracellular proteins in aging have been understudied. Here we use proximity labeling followed by quantitative proteomics to systema...
