Recombinant Human Peptidyl-prolyl cis-trans isomerase E (PPIE)

Uniprot Id

Q9UNP9

Target Species

Human

Target Name

PPIE

Target Full Name

Peptidyl-prolyl cis-trans isomerase E

Target Function

Involved in pre-mRNA splicing as component of the spliceosome. Combines RNA-binding and PPIase activities. 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. Catalyzes the cis-trans isomerization of proline imidic peptide bonds in proteins. Inhibits KMT2A activity; this requires proline isomerase activity.

Target Subcellular Location

Nucleus.

Target Protein Families

Cyclophilin-type PPIase family, PPIase E subfamily

Target Tissue Specificity

Found in all the examined tissues including heart, brain, placenta, lung, liver, skeletal muscle, kidney and pancreas.

Target Background

The protein encoded by this gene is a member of the peptidyl-prolyl cis-trans isomerase (PPIase) family. PPIases catalyze the cis-trans isomerization of proline imidic peptide bonds in oligopeptides and accelerate the folding of proteins. This protein contains a highly conserved cyclophilin (CYP) domain as well as an RNA-binding domain. It was shown to possess PPIase and protein folding activities, and it also exhibits RNA-binding activity. Alternative splicing results in multiple transcript variants. A related pseudogene, which is also located on chromosome 1, has been identified.
