CFTR and cystic fibrosis: We also observed expected enrichments related to protein folding, quality control and degradation, including various terms related to the unfolded protein response (UPR), “ubiquitin-mediated proteolysis”, “ubiquitin cycle”, and CFTR-specific pathways such as “CFTR folding and maturation, normal and CF” and “Regulation of degradation of ΔF508-CFTR in CF”.
