Cyclophilin E,cyclophilin-33,CYP33,CYP-33,peptidyl-prolyl cis-trans isomerase E,peptidylprolyl isomerase E (cyclophilin E),PPIase E,rotamase E.
Involved in pre-mRNA splicing as component of the spliceosome (PubMed:11991638, PubMed:28076346). Combines RNA-binding and PPIase activities (PubMed:8977107, PubMed:18258190, PubMed:20677832, PubMed:20460131). Binds mRNA and has a preference for single-stranded RNA molecules with poly-A and poly-U stretches, suggesting it binds to the poly(A)-region in the 3-UTR of mRNA molecules (PubMed:8977107, PubMed:18258190, PubMed:20460131). Catalyzes the cis-trans isomerization of proline imidic peptide bonds in proteins (PubMed:8977107, PubMed:18258190, PubMed:20677832, PubMed:20541251). Inhibits KMT2A activity, this requires proline isomerase activity (PubMed:20677832, PubMed:20541251, PubMed:20460131).
