p53 Antibodies, Proteins & Kits

Tumor antigen p53 is found in the cytoplasm, nucleus, and endoplasmic reticulum. It functions as a tumor suppressor within a variety of tumors by either stimulating apoptosis or growth arrest in deference to cell type and physiological factors. p53 negatively regulates cell division during cell cycle regulation. It is also thought to be involved in the cross-over for Notch signaling. Defects in p53 expression have been implicated in several diseases including; choroid plexus papilloma, lung cancer, head/neck squamous cell carcinomas, esophageal squamous cell carcinoma, Li-Fraumeni syndrome, and hereditary adrenocortival carcinoma.
