The inhibitor is a ribonucleoprotein sedimenting at 5–6 S with a M r , of ~ 84 000 ± 6000. The particle is composed of a protein with M r of 64 000 and an RNA with a length of 85 ± 2 nucleotides and is a very potent inhibitor of the translation of mRNA. The inhibition is a property of the RNA but the inhibitor ribonucleoprotein is more efficient in the inhibition of poly(A) containing mRNA than its extracted RNA.
