Mouse Anti-Canine Tumor Protein p53 Monoclonal Antibody

p53, also known as tumor protein p53 or TP53, is a multifunctional protein that plays a central role in the regulation of the cell cycle and apoptosis. It is often referred to as the "guardian of the genome" due to its crucial function in preventing cancer formation. p53 is activated in response to DNA damage, hypoxia, and other cellular stresses, and it mediates cell cycle arrest, allowing time for DNA repair or triggering apoptosis if the damage is irreparable. The protein is involved in a wide range of cellular processes, including senescence, DNA repair, and the maintenance of genomic stability. It achieves these functions by acting as a transcription factor that regulates the expression of numerous target genes involved in cell cycle control, apoptosis, and DNA repair.
