Immunogen:synthetic peptide. The epitope recognized by A300-352A maps to a region between residue 400 and 450 of human Ubiquitin Protein Ligase E3A using the numbering given in entry NP_000453.2 (GeneID 7337).
Bemerkungen:E6AP is an E3 ubiquitin ligase. Inheritance of a mutant maternal copy of this gene results in Angelman syndrome (AS) which is characterized by severe mental retardation, seizures, ataxia, and EEG abnormalities. E6AP interacts with the type 16 and 18 human papillomavirus E6 oncoprotein which results in the targeting of p53 for degradation via the ubiquitin-proteasome system. Alternate names for E6AP include ubiquitin-protein ligase E3A, E6AP ubiquitin-protein ligase, oncogenic protein-associated protein E6-AP, human papillomavirus E6-associated protein, renal carcinoma antigen NY-REN-54, UBE3A, E6AP, EPVE6AP, HPVE6A, AS, ANCR, and FLJ26981.
Rabbit anti-E6AP Antibody, Affinity Purified
Detection of Human and Mouse E6AP by Western Blot and Immunoprecipitation. Samples: Whole cell lysate from HeLa (5, 15 and 50 mcg for WB; 1 mg for IP, 20% of IP loaded), 293T (T; 50 mcg), and mouse NIH3T3 (M; 50 mcg) cells. Antibodies: Affinity purified rabbit anti-E6AP antibody A300-352A (lot A300-352A-2) used for WB at 0.4 mcg/ml (A) and 1 mcg/ml (B) and used for IP at 3 mcg/mg lysate. E6AP was also immunoprecipitated by rabbit anti-E6AP antibody A300-351A, which recognizes an upstream epitope. Detection: Chemiluminescence with exposure times of 3 minutes (A and B).
