Protein attributes

Sequence length	161 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. May be involved in pre-mRNA splicing.
Catalytic activity	Peptidylproline (omega=180) = peptidylproline (omega=0).
Subunit structure	Identified in the spliceosome C complex.
Tissue specificity	Ubiquitous. Detected at low levels. Ref.1
Sequence similarities	Belongs to the cyclophilin-type PPIase family. PPIL3 subfamily. Contains 1 PPIase cyclophilin-type domain.
