TheE6-APgene (UBE3A) encodes an E3 ubiquitin–protein ligase that binds the human
papillomavirus E6 oncoprotein and catalyzes the ubiquitination of p53. Recent studies have
also established that mutations inE6-APare the genetic basis of the Angelman syndrome in
humans. In this study we present the genomic structure of the coding region ofE6-APand an
analysis of a set of fiveE6-APmRNAs with the potential to encode three protein isoforms of
the E6-AP protein (isoforms I, II, and III) that differ at their extreme amino-termini. These …

These transcripts were expressed in a variety of different cell lines examined.
