Characteristics 1. Since applications vary, each investigator should titrate the reagent to obtain optimal results.
2. Please refer to us for technical protocols.
3. Caution: Sodium azide yields highly toxic hydrazoic acid under acidic conditions. Dilute azide compounds in running water before discarding to avoid accumulation of potentially explosive deposits in plumbing.
Purification Purified from tissue culture supernatant or ascites by affinity chromatography.
Alternative Name p73 (TP73 Antibody Abstract)
Background P53 is a tumor suppressor which acts as an S-phase checkpoint for DNA damage. The gene for p53 is the most commonly mutated gene identified in human cancers. Recently, a new member of the p53 family, p73, was identified. p73 is structurally homologous to p53 in several regions, including the p53 N-terminal transactivation domain and Cterminal oligomerization domains, as well as the region corresponding to the p53 DNA-binding domain. When overexpressed, p73 can promote p53-like functions, including induction of apoptosis and induction of transcription from p53-responsive promotors such as p21. Despite structural and apparent functional homology, data suggests that these proteins may have distinct functions as well. For example, viral oncoproteins such as Adenovirus E1B 55K and HPV E6, which bind to and thus inactivate p53 during the process of transformation, do not bind to p73. In addition, unlike p53, p73 expression is not induced by DNA damage, e.g. UV irradiation. Several p73 splice variants have been identified, including alpha (full length), beta (missing exon 13), gamma (missing exon 11) and delta (missing exons 11, 12 and 13). Two hybrid analysis has shown variable interaction(s) between these isoforms in vitro. Many types of normal, tumor and virally-transformed cell lines express detectable levels of p73, however, the relative expression of p73 isoforms, as well as their functional activity, appears to be differentially regulated in various cell types. p73alpha and beta isoforms migrate at molecular weights of aproximately 80 kDa (alpha) and 70 kDa (beta), respectively. The ER-13 antibody reacts with human p73alpha and beta. A 73alpha:GST fusion protein containing amino acids 380-367 of human p73alpha was used as immunogen.
Molecular Weight 70-80 kDa
Research Area Cancer, Cell Cycle, Transcription Factors, DNA/RNA
Application Notes The ER-13 antibody is recommended for western blot analysis4 (1-2 µg/ml). Other applications not routinely tested include immunoprecipitation. Human cell lines including 293 adenovirus-transformed kidney cells (ATCC CRL-1573) and Cos-7 SV-40 transformed monkey kidney (ATCC CRL-1651) cell lines are recommended as positive controls for these applications.
