Human PPIG (alias: SR-Cyp, CARS) is a cyclophilin, an enzyme that interconverts cis and trans isomers of proline. The PPIG gene, in addition to the cyclophilin domain, encodes for a multiple C-terminal SR motifs. PPIG associates with the human spliceosome, the complex and dynamic machinery that removes intronic sequence from pre-messenger RNA (pre-mRNA). Nothing is known about the function of PPIG in regulation of alternative splicing. To understand the function of PPIG, we knocked down PPIG in human cells. We characterized a set of alternative splicing and transcriptional events that are PPIG-responsive. We used these splicing and transcriptional bioassays to show that PPIG-responsive events are largely specific, even within the cyclophilin family.
Overall design 3 replicates of PPIG knockdown cell lines (HEK293T cells, stably integrated, selected using puro, MISSION shRNA (TRCN0000049326, 5'-CCGGGCAGTCTGATTCTAAAGGAAACTCGAGTTTCCTTTAGAATCAGACTGCTTTTTG-3'). 3 replicates of SCR control cells lines (HEK293T cells, stably integrated, selected using puro, sequence 5′-CCTAAGGTTAAGTCGCCCTCGCTCTAGCGAGGGCGACTTAACCTT-3′). total RNA purified from ~1 million cells, cDNA converted using random hexamer primers, quantity measured using NanoDrop, quality quantified using BioAnaylzer).
