CC -!- FUNCTION: Required for pre-mRNA splicing as component of the
CC spliceosome. As a component of the minor spliceosome, involved in the
CC splicing of U12-type introns in pre-mRNAs (By similarity). Promotes
CC exon-junction complex (EJC) assembly. Hinders EIF4A3 from non-
CC specifically binding RNA and escorts it to the splicing machinery to
CC promote EJC assembly on mature mRNAs. Through its role in EJC assembly,
CC required for nonsense-mediated mRNA decay.
CC {ECO:0000250|UniProtKB:Q9HCG8}.
CC -!- SUBUNIT: Component of the pre-catalytic spliceosome B and the catalytic
CC spliceosome C complexes. Component of the minor spliceosome, which
CC splices U12-type introns (By similarity). Interacts with EIF4A3 and
CC PRPF19 in an RNA-independent manner. Direct interaction with EIF4A3 is
CC mediated by the MIF4G domain. Full interaction with EIF4A3 occurs only
CC when EIF4A3 is not part of the EJC and prevents EIF4A3 binding to RNA.
CC {ECO:0000250|UniProtKB:Q9HCG8}.
CC -!- SUBCELLULAR LOCATION: Nucleus {ECO:0000250|UniProtKB:Q9HCG8}. Nucleus
CC speckle {ECO:0000250|UniProtKB:Q9HCG8}. Note=Concentrates around
CC speckles, which are sites of pre-mRNA synthesis and processing, where
CC it colocalizes with EJC core proteins. {ECO:0000250|UniProtKB:Q9HCG8}.
CC -!- ALTERNATIVE PRODUCTS:
CC Event=Alternative splicing; Named isoforms=2;
CC Name=1;
CC IsoId=Q8C5N3-1; Sequence=Displayed;
CC Name=2;
CC IsoId=Q8C5N3-2; Sequence=VSP_027905;
CC -!- SIMILARITY: Belongs to the CWC22 family. {ECO:0000305}.
CC -!- SEQUENCE CAUTION:
CC Sequence=AAH03993.1; Type=Erroneous initiation; Evidence={ECO:0000305};
