Ube3a-ATS characterization with strand-speicific microarray

ABSTRACT: This strand-specific array is performed to characterize expression features of Ube3a-ATS, including its imprinting status, its exon-intron structure, its transcriptional initiation and termination site as well as its polyadenylation status. The array contains reverse-complementary probes detecting transcripts from both strands and therefore we are able to pick up signal from both Ube3a sense and antisense. By comparing wild-type with various mutants, and total RNA with polyA RNA, we concluded that Ube3a-ATS is a paternally imprinted gene covering the whole gene body of Ube3a in the antisense orientation. It does not have an obvious exon-intron structure. Its transcription initiates at Snrpn major promoter and terminates ~40kb upstream of Ube3a transcriptional start site. Total RNA from Snr
