The insertion of selenocysteine (Sec) during translation involves a unique set of specialized translational cofactors, including a Sec-specific elongation factor, a tRNA Sec that recognizes the UGA codon, and RNA binding proteins, such as SBP2 (SECIS binding protein 2) that bind to stem-loop structures in the 3-untranslated region of the selenoprotein transcripts denoted selenocysteine incorporation sequence or SECIS (for review see [64, 65])
