Summary of New study using cryo-electron microscopy shows how potential drugs could inhibit cancer
A new study used cryo-electron microscopy (cryo-EM) to visualize, at atomic resolution, how a potential small-molecule drug binds to the p97 enzyme, a protein involved in cellular protein regulation and a promising anti-cancer target. The cryo-EM structures also revealed the precise sequence of conformational changes p97 undergoes during its normal function, informing how inhibitors could block its activity.
Parts used in theCryo-EM study of p97:
- Cryo-electron microscope
- Purified p97 protein samples
- Potential small-molecule inhibitor (drug candidate)
- Vitrification equipment (for sample freezing)
- Image processing and reconstruction software
- Computational tools for atomic model building and refinement
A new study shows that it is possible to use an imaging technique called cryo-electron microscopy (cryo-EM) to view, in atomic detail, the binding of a potential small molecule drug to a key protein in cancer cells. The cryo-EM images also helped the researchers establish, at atomic resolution, the sequence of structural changes that normally occur in the protein, p97, an enzyme critical for protein regulation that is thought to be a novel anti-cancer target.
