Threading the needle: getting selenocysteine into proteins

Open access

Abstract

The co-translational incorporation of selenocysteine (Sec) requires that UGA be recognized as a sense rather than a nonsense codon. This is accomplished by the concerted action of a Sec insertion sequence (SECIS) element, SECIS binding protein 2, and a ternary complex of the Sec specific elongation factor, Sec-tRNA(Sec), and GTP. The mechanism by which they alter the canonical protein synthesis reaction has been elusive. Here we present an overview of the mechanistic perspective on Sec incorporation, highlighting recent advances in the field.

  • SBP2 binds the SECIS element in the 3' UTR of selenoprotein mRNAs and helps insert tRNA(Sec) into the ribosomal complex at the internal UGA site.

    “Selenocysteine insertion sequence binding protein 2 (SECISBP2; SBP2) binds to a stem loop RNA structure (Sec insertion sequence [SECIS] element) located in 3’-UTR region of selenoprotein mRNAs, and facilitates the incorporation of tRNA(Sec) into the ribosomal complex at the internal UGA site [68].”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
