Global analysis of pre-mRNA subcellular localization following splicing inhibition by spliceostatin A.
Spliceostatin A (SSA) is a methyl ketal derivative of FR901464, a potent antitumor compound isolated from a culture broth of Pseudomonas sp no. 2663. These compounds selectively bind to the essential spliceosome component SF3b, a subcomplex of the U2 snRNP, to inhibit pre-mRNA splicing. However, the mechanism of SSA's antitumor activity is unknown. It is noteworthy that SSA causes accumulation ...
متن کاملGlobal analysis of positive and negative pre-mRNA splicing regulators in Drosophila.
To gain insight into splicing regulation, we developed a microarray to assay all annotated alternative splicing events in Drosophila melanogaster and identified the alternative splice events controlled by four splicing regulators: dASF/SF2, B52/SRp55, hrp48, and PSI. The number of events controlled by each of these factors was found to be highly variable: dASF/SF2 strongly affects >300 splicing...
متن کاملFunctional analysis of the polypyrimidine tract in pre-mRNA splicing.
The polypyrimidine tract is one of the important cis-acting sequence elements directing intron removal in pre-mRNA splicing. Progressive deletions of the polypyrimidine tract have been found to abolish correct lariat formation, spliceosome assembly and splicing. In addition, the polypyrimidine tract can alter 3'-splice site selection by promoting alternative branch site selection. However, ther...
متن کاملAnalysis of pre-mRNA splicing using HeLa cell nuclear extracts.
This protocol is used to determine the splicing behavior of pre-mRNAs in cell extracts that are capable of carrying out splicing (e.g., nuclear extracts from HeLa cells). (32)P-labeled RNA is incubated under splicing conditions for various times, and the resulting products are analyzed on denaturing polyacrylamide gels.
متن کاملGenome-wide analysis of alternative pre-mRNA splicing.
Alternative splicing of mRNA precursors allows the synthesis of multiple mRNAs from a single primary transcript, significantly expanding the information content and regulatory possibilities of higher eukaryotic genomes. High-throughput enabling technologies, particularly large-scale sequencing and splicing-sensitive microarrays, are providing unprecedented opportunities to address key questions...
