Abstract

Selenocysteine (Sec) is cotranslationally inserted into polypeptides during the elongation phase of protein synthesis in response to specific UGA codons. As UGA normally signals translation termination, the Sec incorporation complex is required to modify the canonical translation machinery. Thus, a thorough understanding of the Sec incorporation mechanism necessitates careful consideration of the intricacies of general translation, specifically during the elongation phase. Here, we consider the current body of evidence that supports a key role for the ribosome in regulating the process of Sec incorporation.
