Such conformational changes are an important aspect of protein function and are displayed in the video as a dynamic computer-generated morph between two distinct structural states, which were determined experimentally.
P53 was first described as a transcription factor in the early 90’s. It is an important tumor suppressor, referred to as “guardian of the genome” because it can react to DNA damage by holding the cell cycle progression and giving time for DNA repair proteins to act. It is implicated in ageing and has the potential to induce apoptosis in cells that cannot fix DNA damage.
