This subproject is one of many research subprojects utilizing theresources provided by a Center grant funded by NIH/NCRR. The subproject andinvestigator (PI) may have received primary funding from another NIH source,and thus could be represented in other CRISP entries. The institution listed isfor the Center, which is not necessarily the institution for the investigator.Messenger RNA in eukaryotes must be post-transcriptionally modified at its end in order to reach the cytoplasm, to function efficiently in translation, and to be properly removed when its job is done. This process also serves as a point at which the cell can regulate the type and amount of mRNA derived from a particular gene and affect the fate of the cell. This processing event is executed by a large complex of proteins whose architecture is poorly understood. We will use a technique that detects protein/protein interactions in living cells to help us understand how this complex performs its critical function.
