Sentence examples for branches site from inspiring English sources

In the present ML analysis, Anthosachne scabra (StYW, PI533213, Australia) was placed at abnormal branches site with St-type nrITS sequences obtained from Pse. libanotica (St, Middle East), Pse.

The generation of branched tissues requires regulation of branch site specification, initiation and elongation.

A novel mechanism for Prp5 function in prespliceosome formation and proofreading the branch site sequence.

Splicing to the new AG uses the upstream branch site exclusively, presumably because the downstream branch site is only 4 nt from this 3' splice site.

We have previously used site-directed mutagenesis to introduce an additional branch site into the first intron of the human beta-globin gene at nt -24 between the natural branch site (nt -37) and the normal 3' splice site (nt -1).

We found that either the upstream or downstream branch site could be used during in vitro splicing, depending on which site best matched the mammalian branch site consensus YURAC (R = purine; Y = pyrimidine).

We show here that use of the normal 3' splice site can be restored either by improving the match of a cryptic branch site to the branch site consensus or by introducing mutant U2 snRNAs with greater complementarity to the cryptic branch site.

Another possibility is that this motif positions the branch site for interaction with the U2 snRNP.

The likely U2-candidate shown in Figure 2B contains a "UAGUU" motif which complements the 5' of intron branch site "AACUG (or AACUA)", but does not have upstream bases that can bind to 3' of the branch-site adenosine (coloured red), thus instead of leaving the branch-site adenosine bulged this interaction leaves an open-end at the branch site.

BS, branch site; PPT, polypyrimidine tract; SS, splice site.

The U2AF factor then recruits U2 to the branch site.
