Target Information

Eukaryotes require a selenocysteine (Sec) insertion sequence (SECIS) element in the 3′ untranslated region of the mRNA to decode the UGA codon as Sec.
SECIS-binding protein 2 (SBP-2) specifically binds selenoprotein mRNAs to form a functional complex and is essential for the insertion of Sec into selenoproteins.
Purified SBP-2 interacts specifically with the SECIS element in the phospholipid hydroperoxide glutathione peroxidase mRNA.
SBP-2 shows binding activity in the liver and testis as well as hepatoma cells.
It binds to a conserved RNA binding domain shared with several ribosomal proteins and eukaryotic translation termination release factor 1.
A second domain located N-terminal to the RNA binding domain, required for Sec insertion, allows SBP-2 to stably associate with the ribosomal fraction of cells.
SBP-2 preferentially stimulates incorporation directed by the selenoprotein P and phospholipid hydroperoxide glutathione peroxidase SECIS elements.
SBP-2 may have a distinct function in selecting the ribosomes for Sec insertion.
