CC -!- FUNCTION: Plays a role in pre-mRNA splicing as a core component of the
CC spliceosomal U1, U2, U4 and U5 small nuclear ribonucleoproteins
CC (snRNPs), the building blocks of the spliceosome.
CC {ECO:0000250|UniProtKB:P62316}.
CC -!- SUBCELLULAR LOCATION: Nucleus {ECO:0000250|UniProtKB:P62316}.
CC Cytoplasm, cytosol {ECO:0000250|UniProtKB:P62316}.
CC -!- SIMILARITY: Belongs to the snRNP core protein family. {ECO:0000305}.
