CC -!- FUNCTION: Involved in pre-mRNA splicing as a component of the
CC spliceosome (By similarity). Regulates alternative splicing of the
CC HSPG2 pre-mRNA (By similarity). Required for normal accumulation of IK
CC (By similarity). Required for normal mitotic spindle assembly and
CC normal progress through mitosis (By similarity).
CC {ECO:0000250|UniProtKB:Q2TAY7, ECO:0000250|UniProtKB:Q76B40}.
CC -!- SUBUNIT: Component of the spliceosome B complex. Interacts with IK.
CC {ECO:0000250|UniProtKB:Q2TAY7}.
CC -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000250|UniProtKB:Q99M63}. Nucleus
CC {ECO:0000250|UniProtKB:Q76B40}. Nucleus speckle
CC {ECO:0000250|UniProtKB:Q76B40}. Note=Colocalizes with SRSF1 in nuclear
CC speckles. {ECO:0000250|UniProtKB:Q76B40}.
CC -!- DOMAIN: The WD repeats assemble into a seven-bladed WD propeller.
CC {ECO:0000250|UniProtKB:G5EEG7}.
CC -!- SIMILARITY: Belongs to the WD repeat SMU1 family. {ECO:0000305}.
