| Abstract |
A free cytoplasmic 22 S ribonucleoprotein particle exhibiting a major template activity in rabbit reticulocyte system has been identified in the crypto-biotic gastrulae of Artemia salina. This particle contains non-polyadenylated 9 S messenger UNA which codes primarily for a non-histone basic protein with an apparent molecular weight of 26 000 daltons.We have previously demonstrated the presence of a translational inhibitor RNA which is apparently responsible for transforming polyadenylated messenger ribonucleoproteins into a repressed state in the cryptobiotic gastrulae (Siegers et al., FEBS Letters 80, 390–394, 1977). This inhibitor RNA was found to be completely ineffective on the template activity of non-polyadenylated 22 S messenger ribonucleoprotein, confirming the specificity of this regulatory RNA for polyadenylate sequences. |
