CC -!- FUNCTION: Involved in pre-mRNA splicing as component of the
CC spliceosome. Combines RNA-binding and PPIase activities. Binds mRNA and
CC has a preference for single-stranded RNA molecules with poly-A and
CC poly-U stretches, suggesting it binds to the poly(A)-region in the 3'-
CC UTR of mRNA molecules. Catalyzes the cis-trans isomerization of proline
CC imidic peptide bonds in proteins. Inhibits KMT2A activity; this
CC requires proline isomerase activity. {ECO:0000250|UniProtKB:Q9UNP9}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=[protein]-peptidylproline (omega=180) = [protein]-
CC peptidylproline (omega=0); Xref=Rhea:RHEA:16237, Rhea:RHEA-
CC COMP:10747, Rhea:RHEA-COMP:10748, ChEBI:CHEBI:83833,
CC ChEBI:CHEBI:83834; EC=5.2.1.8;
CC Evidence={ECO:0000250|UniProtKB:Q9UNP9};
CC -!- SUBUNIT: Identified in the spliceosome C complex. Component of the XAB2
CC complex, a multimeric protein complex composed of XAB2, PRPF19, AQR,
CC ZNF830, ISY1, and PPIE. Identified in a pentameric intron-binding (IB)
CC complex composed of AQR, XAB2, ISY1, ZNF830 and PPIE that is
CC incorporated into the spliceosome as a preassembled complex. The IB
CC complex does not contain PRPF19. Interacts (via RNA-binding domain)
CC with KMT2A (via the third PHD-type zinc-finger).
CC {ECO:0000250|UniProtKB:Q9UNP9}.
CC -!- SUBCELLULAR LOCATION: Nucleus {ECO:0000250|UniProtKB:Q9UNP9}.
CC -!- DOMAIN: The RRM domain mediates both interaction with RNA and with
CC KMT2A (via the third PHD-type zinc-finger), but has much higher
CC affinity for the KMT2A PHD-type zinc-finger.
CC {ECO:0000250|UniProtKB:Q9UNP9}.
CC -!- SIMILARITY: Belongs to the cyclophilin-type PPIase family. PPIase E
CC subfamily. {ECO:0000305}.
