CC   -!- FUNCTION: Involved in pre-mRNA splicing. May function at or prior to
CC       the first catalytic step of splicing at the catalytic center of the
CC       spliceosome. May do so by stabilizing the catalytic center or the
CC       position of the RNA substrate (By similarity). {ECO:0000250}.
CC   -!- SUBUNIT: Associates with the NTC complex (or PRP19-associated complex).
CC       The NTC complex associates with the spliceosome after the release of
CC       the U1 and U4 snRNAs and forms the CWC spliceosome subcomplex
CC       reminiscent of a late-stage spliceosome. {ECO:0000250}.
CC   -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000250}. Nucleus {ECO:0000250}.
CC   -!- SIMILARITY: Belongs to the CWC21 family. {ECO:0000305}.
CC   -!- SEQUENCE CAUTION:
CC       Sequence=CAH02369.1; Type=Erroneous initiation; Evidence={ECO:0000305};
