The PPIE gene, in addition to the cyclophilin domain, encodes for an N-terminal RRM. PPIE 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 PPIE in regulation of alternative splicing, although it has been shown to modulate chromatin modification. To further understand the function of PPIE, we knocked down PPIE in human cells. We characterized a set of alternative splicing and transcriptional events that are PPIE-responsiv...
