Protein attributes

Sequence length	172 AA.
Sequence status	Complete.
Protein existence	Evidence at protein 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 By similarity.
Subcellular location	Cytoplasm Probable.
Tissue specificity	Ubiquitous, with higher levels in roots and flowers. Confined to vascular tissues. Also detected in stigmas, base of siliques and anthers. Ref.7 Ref.8 Ref.9
Sequence similarities	Belongs to the cyclophilin-type PPIase family. Contains 1 PPIase cyclophilin-type domain.
