    basic FUNCTION
  • is essential for the cotranslational insertion of sec into selenoproteins
  • may be involved in preventing termination at the UGA/sec codon
  • remains ribosome bound except during selenocysteine delivery to the ribosomal A-site
  • protein of the Sec incorporation machinery, having transcription and translation regulated in a coordinated manner in response to stress (Papp 2008)

    INTERACTION
    DNA
    RNA binding
    small molecule
    protein
  • EIF4A3 interaction with the selenoprotein mRNA prevents the binding of SECISBP2, which is required for selenocysteine insertion, thereby inhibiting the synthesis of the selenoprotein
