Additionally, 'PRP19-related' proteins enter the spliceosome individually or in pre-assemblies that differ in these systems. The protistan family Trypanosomatidae, which harbors parasites such as Trypanosoma brucei, diverged early during evolution from opisthokonts. While introns are rare in these organisms, spliced leader trans splicing is an obligatory step in mRNA maturation. So far, ∼70 proteins have been identified as homologs of human and yeast splicing factors. Moreover, few proteins of unknown function have recurrently co-purified with splicing proteins. Here we silenced the gene of one of these proteins, termed PRC5, and found it to be essential for cell viability and pre-mRNA splicing. Purification of PRC5 combined with sucrose gradient sedimentation revealed a complex of PRC5 with a second trypanosomatid-specific protein, PRC3, and PRP19-related proteins SYF1, SYF3 and ISY1, which we named PRP19-related complex (PRC). Importantly, PRC and the previously described PRP19 complex are distinct from each other because PRC, unlike PRP19, co-precipitates U4 snRNA, which indicates that PRC enters the spliceosome prior to PRP19 and uncovers a unique pre-organization of these proteins in trypanosomes."xsd:string |
