General annotation (Comments)

Function	PPIases accelerate the folding of proteins. Catalyzes the cis-trans isomerization of proline imidic peptide bonds in oligopeptides. Involved in pre-mRNA splicing By similarity.
Catalytic activity	Peptidylproline (omega=180) = peptidylproline (omega=0).
Subunit structure	Belongs to the CWC complex (or PRP19-associated complex), a spliceosome subcomplex composed of the U2, U5 and U6 snRNAs and at least BUD13, BRR2, CDC40, CEF1, CLF1, CUS1, CWC2, CWC15, CWC21, CWC22, CWC23, CWC24, CWC25, CWC27, ECM2, HSH155, IST3, ISY1, LEA1, MSL1, NTC20, PRP8, PRP9, PRP11, PRP19, PRP21, PRP22, PRP45, PRP46, SLU7, SMB1, SMD1, SMD2, SMD3, SMX2, SMX3, SNT309, SNU114, SPP2, SYF1, SYF2, RSE1 and YJU2.
Subcellular location	Cytoplasm. Nucleus Ref.3.
Miscellaneous	Present with 2360 molecules/cell in log phase SD medium. Ref.4
Sequence similarities	Belongs to the cyclophilin-type PPIase family. CWC27 subfamily. Contains 1 PPIase cyclophilin-type domain.
