The p53 tumor suppressor protein plays a major role in cellular response to DNA damage and other genomic aberrations. It is situated at the crossroads of signalling pathways that are essential for cell growth regulation and apoptosis. In normal unstressed cells, the level of p53 protein is downregulated via the binding of proteins such as MDM2, COP1, PIRH2 or JNK that promote p53 degradation via the ubiquitin/proteasome pathway. As most of these genes are up regulated by p53, this lead to a regulation loop that will keep p53 level very low in a normal cells. Alternative splicing of the human p53 gene gives rise of p53 beta, p53 gamma, Delta 40p53 (also known as p44, p47 or delat N p53), Delta 40p53 beta, Delta 40 p53 gamma, Delta 133p53, Delta 133p53 beta, and Delta 133p53 gamma. p53 Antibody (5E8A3), mAb, Mouse is produced from the hybridoma resulting from fusion of SP2/0-Ag14 myeloma and B-lymphocytes obtained from mouse immunized with human recombinant wild type p53 (wt p53).

For Research Use Only. Not for use in diagnostic/therapeutics procedures.
|Post transnational modification:||Sumoylated with SUMO1. Sumoylated at Lys-386 by UBC9.|
|Tissue Specificity:||Ubiquitous. Isoforms are expressed in a wide range of normal tissues but in a tissue-dependent manner. Isoform 2 is expressed in most normal tissues but is not detected in brain, lung, prostate, muscle, fetal brain, spinal cord and fetal liver. Isoform 3 is expressed in most normal tissues but is not detected in lung, spleen, testis, fetal brain, spinal cord and fetal liver. Isoform 7 is expressed in most normal tissues but is not detected in prostate, uterus, skeletal muscle and breast. Isoform 8 is detected only in colon, bone marrow, testis, fetal brain and intestine. Isoform 9 is expressed in most normal tissues but is not detected in brain, heart, lung, fetal liver, salivary gland, breast or intestine.|
