Protein
Peptidyl-prolyl cis-trans isomerase H
Gene
PPIH, CYP20, CYPH
Organism
Homo sapiens (Human)
Status
Reviewed - Annotation score: 5 out of 5 - Experimental evidence at protein leveli

Functioni

PPIases accelerate the folding of proteins. It catalyzes the cis-trans isomerization of proline imidic peptide bonds in oligopeptides. Participates in pre-mRNA splicing. May play a role in the assembly of the U4/U5/U6 tri-snRNP complex, one of the building blocks of the spliceosome. May act as a chaperone.3 Publications

Catalytic activityi

Peptidylproline (omega=180) = peptidylproline (omega=0).

Enzyme regulationi

Inhibited by cyclosporin A.
