Protein attributes

Sequence length	309 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. Thought to function as a catalyst in the folding and modification of cuticle collagens. Ref.2
Catalytic activity	Peptidylproline (omega=180) = peptidylproline (omega=0).
Tissue specificity	Co-expressed with pdi-1 in the syncytial hypodermis. Ref.2
Developmental stage	Expression significantly up-regulated in the middle of the L3 (22 hours) and L4 (26 hours) larval stages. Ref.2
Sequence similarities	Belongs to the cyclophilin-type PPIase family. Contains 1 PPIase cyclophilin-type domain.
