TLDR
Evidence is provided that dietary selenium deficiency shortens, while supplementation of the diet withSelenium normalizes the Drosophila life span by a process that may involve the newly identified selenoproteins.

Characterization of Mammalian Selenoproteomes

TL;DR: This work identified selenoprotein genes in sequenced mammalian genomes by methods that rely on identification of selenocysteine insertion RNA structures, the coding potential of UGA codons, and the presence of cysteine-containing homologs.

Evolution of genes and genomes on the Drosophila phylogeny.

- 08 Nov 2007 - 
TL;DR: These genome sequences augment the formidable genetic tools that have made Drosophila melanogaster a pre-eminent model for animal genetics, and will further catalyse fundamental research on mechanisms of development, cell biology, genetics, disease, neurobiology, behaviour, physiology and evolution.
Journal ArticleDOI

Selenoproteins: molecular pathways and physiological roles.

TL;DR: Current knowledge about how these unique proteins perform their functions at the molecular level is discussed and new insights into the roles that selenoproteins play in human health are highlighted.
Journal ArticleDOI

How selenium has altered our understanding of the genetic code.

TL;DR: While the fundamental mechanism of Sec insertion in these organisms appears to be similar, recent studies suggest that mammals evolved additional components that allow incorporation of multiple Secs into a single protein and provide stringent regulation of Sec biosynthesis.
Journal ArticleDOI

A holidic medium for Drosophila melanogaster

TL;DR: A holidic medium is described that is equal in performance to an oligidic diet optimized for adult fecundity and lifespan and it is reported that folic acid from the microbiota is sufficient for Drosophila development.

Cooperative regulation of cell polarity and growth by Drosophila tumor suppressors.

TL;DR: It is shown that the tumor suppressors lethal giant larvae (lgl) and discs-large (dlg) have identical effects on all three epithelia, and that scrib also acts as a tumor suppressor.
Journal ArticleDOI

Knowing when not to stop: selenocysteine incorporation in eukaryotes.

TL;DR: The regulation of translation frequently involves protein-RNA interactions, and in prokaryotes a single RNA-binding protein, a selenocysteine-specific elongation factor, interacts with both the tRNA and mRNA to confer decoding.
Journal ArticleDOI

A novel RNA binding protein, SBP2, is required for the translation of mammalian selenoprotein mRNAs

TL;DR: It is established that SBP2 is essential for the co‐translational insertion of Sec into selenoproteins and hypothesize that the binding activity of SBp2 may be involved in preventing termination at the UGA/Sec codon.
Journal ArticleDOI

Decoding apparatus for eukaryotic selenocysteine insertion

TL;DR: expression of the two functional domains of the bacterial elongation factor–SECIS binding protein as two separate proteins in eukaryotes suggests a mechanism for rapid exchange of charged for uncharged selenocysteyl‐tRNA–elongation factor complex, allowing a single SECIS element to serve multiple UGA codons.
