We demonstrate via RNAi coupled with RNA-Seq that two of these human-specific proteins, Smu1 and RED, function both as alternative splicing regulators and as general splicing factors and are required predominantly for efficient splicing of short introns. In vitro splicing assays reveal that Smu1 and RED promote spliceosome activation, and are essential for this step when the distance between the pre-mRNA's 5' splice site (SS) and branch site (BS) is sufficiently short. This Smu1-RED requirement can be bypassed when the 5' and 3' regions of short introns are physically separated. Our observations suggest that Smu1 and RED relieve physical constraints arising from a short 5'SS-BS distance, thereby enabling spliceosomes to overcome structural challenges associated with the splicing of short introns."xsd:string |
