CC -!- FUNCTION: Involved in pre-mRNA splicing as a component of the
CC spliceosome (By similarity). Required for normal accumulation of ik (By
CC similarity). Required for normal mitotic spindle assembly and normal
CC 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}.
