RNA-Seq of control and RNPS1 knockdown with or without RNPS1-RRM domain rescue in HeLa Tet-Off cells

RNPS1 is a splicing regulatory protein and a component of the ASAP/PSAP complex, which is associated with the exon junction complex and modulates alternative splicing. It was previously postulated that the isolated RRM domain of RNPS1 in complex with ASAP/PSAP is able to regulate certain alternative splicing events. We aimed to investigate in HeLa Tet-Off cells which alternative splicing events are rescued by the expression of the isolated RRM domain of RNPS1 in a RNPS1 knockdown background by using RNA-Seq analyses. The rescue construct was stably integrated into the genome using the PiggyBac transposon system. As controls, either Luciferase (Luc) siRNA was used or RNPS1 was knocked down without rescue.
