Protein attributes

Sequence length	171 AA.
Sequence status	Complete.
Sequence processing	The displayed sequence is not processed.
Protein existence	Evidence at transcript level.

General annotation (Comments)

Function	PPIases accelerate the folding of proteins. It catalyzes the cis-trans isomerization of proline imidic peptide bonds in oligopeptides.
Catalytic activity	Peptidylproline (omega=180) = peptidylproline (omega=0).
Enzyme regulation	Binds cyclosporin A (CsA). CsA mediates some of its effects via an inhibitory action on PPIase.
Subcellular location	Cytoplasm.
Sequence similarities	Belongs to the cyclophilin-type PPIase family. Contains 1 PPIase cyclophilin-type domain.
