- Abstract
- We screened the Dictyostelium discoideum two-hybrid cDNA library with the SNW/SKIP transcription coregulator SnwA and identified a novel cyclophilin CypE. Independently, the Schizosaccharomyces pombe cDNA library was screened with the SnwA ortholog Snw1 and the ortholog of CypE (named Cyp2) was found. Both cyclophilins bind the respective SNW protein in their autologous systems. The interaction was localized to the N-terminal part of SnwA as well as of Snw1. CypE was confirmed in vitro to be a cyclosporin A-sensitive peptidyl-prolyl cis-trans isomerase. Remarkably, both SNW proteins bind the cyclophilins in a cyclosporin A independent manner, possibly serving as adaptors for these novel isomerases. These results are the first characterization of the members of a novel cyclophilin subfamily, which includes the human CGI-124/PPIL1 protein.
