Halving the selenophosphate synthetase gene dose confers hypersensitivity to oxidative stress in Drosophila melanogaster.

abstract：:We report that the rat beta 3-adrenergic receptor (beta 3-AR) gene has an intron. The intron starts with an in-frame stop codon with the result that unspliced transcripts will encode a C-terminal truncated protein. The reported protein sequences of mouse and human beta 3-AR were both deduced from genomic DNA sequences...
