Antibody blocking programmed cell death, illustration. Antibody (yellow) blocking PD-1 (programmed cell death protein 1, red) to prevent it interacting with a surface protein called PD-L1 (orange). Cancer cells (membrane across top) express PD-L1...

DNA binding to anti-cancer protein p53. Molecular model of DNA (pink) binding to the anti-cancer protein p53 (also known as tumour protein 53, or TP53). This protein's action at the cellular level plays a role in repairing DNA (deoxyribonucleic acid),...

Programmed cell death in immune system, illustration. The protein PD-1 (programmed cell death protein 1, red) is seen extending from the surface membrane of a T-cell (across bottom), interacting with the ligand protein PD-L1 (orange) from an antigen...

DNA binding to anti-cancer protein p53. Molecular model of DNA (pink) binding to the anti-cancer protein p53 (also known as tumour protein 53, or TP53). This protein plays a role in repairing DNA (deoxyribonucleic acid), and can be activated by and...

Proteasome, illustration. Proteasomes are large protein-digesting molecular machines that degrade unneeded or damaged proteins (red) that have been tagged with polyubiquitin (a chain of multiple ubiquitin molecules, yellow). This protein degradation...
