Hijacking our cells’ enzymes to eliminate disease-causing proteins
The researchers looked at a ubiquitin ligase enzyme named FBXL2, known to degrade proteins at various cellular membrane compartments. They found that by attaching or detaching a fat molecule or lipid to FBXL2 — a process called palmitoylation and de-palmitoylation — they could direct where the FBXL2 went. They also discovered that in order to travel in the aqueous cellular environment for the delivery of lipid-modified FBXL2 to membrane compartments, it used a trafficking protein called PDE6D, which is known to shield the lipid modifications.
