Novel Exon of Mammalian ADAR2 Extends Open Reading Frame
BACKGROUND The post-transcriptional processing of pre-mRNAs by RNA editing contributes significantly to the complexity of the mammalian transcriptome. RNA editing by site-selective A-to-I modification also regulates protein function through recoding of genomically specified sequences. The adenosine deaminase ADAR2 is the main enzyme responsible for recoding editing and loss of ADAR2 function in...
متن کاملAn upstream open reading frame within an IRES controls expression of a specific VEGF-A isoform
Vascular endothelial growth factor A (VEGF-A) is a potent secreted mitogen critical for physiological and pathological angiogenesis. Regulation of VEGF-A occurs at multiple levels, including transcription, mRNA stabilization, splicing, translation and differential cellular localization of various isoforms. Recent advances in our understanding of the posttranscriptional regulation of VEGF-A are ...
متن کاملSURVEY AND SUMMARY A profusion of upstream open reading frame mechanisms in polyamine-responsive translational regulation
In many eukaryotic mRNAs one or more short ‘upstream’ open reading frames, uORFs, precede the initiator of the main coding sequence. Upstream ORFs are functionally diverse as illustrated by their variety of features in polyamine pathway biosynthetic mRNAs. Their propensity to act as sensors for regulatory circuits and to amplify the signals likely explains their occurrence in most polyamine pat...

متن کاملA conserved upstream open reading frame mediates sucrose-induced repression of translation.
Sugars have been shown to regulate transcription of numerous genes in plants. Sucrose controls translation of the group S basic region leucine zipper (bZIP)-type transcription factor ATB2/AtbZIP11 (Rook et al., 1998a). This control requires the unusually long 5' untranslated region (UTR) of the gene. Point mutations and deletions of the 5'UTR have uncovered the sequences involved. A highly cons...
