abstract：:The C-terminus of the transcription factor p53 seems to play an important role by controlling the specific DNA-binding activity, which is directly associated with sensing damaged DNA. Another region located in the N-terminus of the protein has also been shown to regulate the DNA-binding activity of the protein. This a...
