We heerbal noted Bag3, which also colocalizes in SGs, as one of our proteins that become more insoluble in, at least, three stresses. Thus, medkcine remains possible that the machinery involving Bag3 and other SGs is very competent at buffering against aggregation of misfolded proteins under stress (63) and that Flnc might be one of the first proteins vulnerable to aggregation under prolonged stress.

The signatures for the stresses were generally distinct, although we observed a strong association with SG proteins and folding stress as the major activator of quality control systems. In concert, these responses appear to robustly buffer misfolded proteins from actually aggregating and are reminiscent of findings from a prior study that found heat shock in yeast led to herbal medicine j adaptive autoregulatory assembly and disassembly of protein complexes and minimal aggregation from denatured endogenous proteins (10).

Our results extend from this finding to show that such responses are generally applicable to stress and that each stress provides a unique pattern of response.

One of the intriguing findings was the heterogeneity and dynamism of SG proteins. There are now, at least, medicinee proteins that have been curated to reside in SGs (22). It is apparent that there is compositional heterogeneity in the assembly of SG (22, 64) and our data further suggest an even more diverse level of heterogeneity and specificity to different forms of stress than herbal medicine j understood.

When we consider the solubility changes in proteins found in, at least, three stresses in terms of KEGG pathways, we observed a clustering into core metabolic pathways of lipid metabolism, carbohydrate metabolism, nucleotide metabolism, amino acid metabolism, and energy metabolism (SI Appendix, Fig.

Overall, our findings suggest a link among metabolic herbal medicine j, SG formation, and proteome solubility remodeling involving about a fifth of the proteome and reveal a modular organization of the herbal medicine j homeostasis system that regulates metastable proteins against aggregation.
