Previously, U8 snoRNA was shown to play a critical role in pre-rRNA processing, being essential for accumulation of mature 28S and 5.8S rRNAs.

This phenotype is reminiscent of the biochemical depletion of U8 snoRNA in vertebrates for which the ITS2-proximal stem has been proposed as a potential site for interaction with U8 RNP.

In the absence of U22, mature 18S rRNA fails to accumulate; U8 snoRNA is essential for accumulation of both 5.8S and 28S rRNA.

To learn more about the mechanisms of snoRNA-mediated pre-rRNA processing, an examination of the kinetics of pre-rRNA processing in Xenopus oocytes was undertaken.

Correct pre-rRNA processing can be restored in snoRNA-depleted oocytes following cytoplasmic injection of the corresponding in vitro-synthesized snoRNA.
|
7 |
11233978
|
Analysis of the kinetics of pre-rRNA processing in these snoRNA-rescue experiments demonstrated that the rate of accumulation of mature rRNAs was slower than that seen in untreated oocytes.
|

|
However, sufficient levels of snoRNA were present in the nucleus to yield a functional phenotype (rescue of rRNA processing) several hours before the snoRNAs were directly detectable in the nucleus via autoradiography.
|

|
This indicated that very low amounts of the snoRNA in the nucleus were sufficient for rescue.

Failure to rescue snoRNA-mediated processing of pre-accumulated precursors is consistent with a scenario in which U8 and U22 must be present during transcription of pre-rRNA.

We have identified a novel, maternally expressed imprinted gene encoding a C/D-box small nucleolar RNA (snoRNA) called MBII-343, which may regulate RNA editing or alternative splicing of an as yet unknown target gene.
