Ubiquitin-protein ligase E3A Antibody / UBE3A

SKU: orb2636818

Description

E6-associating protein (E6-AP), also designated ubiquitin protein ligase E3A (UBE3A), is a component of the ubiquitin-mediated proteolytic pathway that selectively targets proteins for degradation by the 26S Proteasome. Ubiquitin(Ub) is directly conjugated to protein substrates by the transfer of Ub from anE2 ubiquitin conjugating enzyme to the target protein. This conjugation is facilitated by the enzymatic activity of E3 ubiquitin ligase family members such asE6-AP. Several substrates of E6-AP have been identified and include the tumor suppressor protein p53 and the mammalian homolog of Rad23, HHR23A.Previous studies have indicated that E6-AP associates with the human papilloma virus E6 oncogene, which forms a complex with p53 and there by potentiates E6-AP mediated ubiquitination of p53. Genetic mutations that impair E6-AP activity result in the accumulation of p53 in the cytoplasm, and in many instances, these mutations are associated with the development of the rare neurodevelopmental disorder Angelman syndrome (AS), which is characterized by severe motor dysfunction and mental retardation.

Analysis of HuProt (TM) microarray containing more than 19000 full-length human proteins using Ubiquitin-protein ligase E3A antibody (clone PCRP-UBE3A-1A2). These results demonstrate the foremost specificity of the PCRP-UBE3A-1A2 mAb. Z- and S- score: The Z-score represents the strength of a signal that an antibody (in combination with a fluorescently-tagged anti-IgG secondary Ab) produces when binding to a particular protein on the HuProt (TM) array. Z-scores are described in units of standard deviations (SD's) above the mean value of all signals generated on that array. If the targets on the HuProt (TM) are arranged in descending order of the Z-score, the S-score is the difference (also in units of SD's) between the Z-scores. The S-score therefore represents the relative target specificity of an Ab to its intended target.
