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. Component of both the
CC pre-catalytic spliceosome B complex and activated spliceosome C
CC complexes. As a component of the minor spliceosome, involved in the
CC splicing of U12-type introns in pre-mRNAs.
CC {ECO:0000256|RuleBase:RU365051}.
CC -!- SUBCELLULAR LOCATION: Cytoplasm, cytosol
CC {ECO:0000256|RuleBase:RU365051}. Nucleus
CC {ECO:0000256|ARBA:ARBA00004123, ECO:0000256|RuleBase:RU365051}.
CC Note=SMN-mediated assembly into core snRNPs occurs in the cytosol
CC before SMN-mediated transport to the nucleus to be included in
CC spliceosomes. {ECO:0000256|RuleBase:RU365051}.
CC -!- SIMILARITY: Belongs to the snRNP core protein family.
CC {ECO:0000256|ARBA:ARBA00008146, ECO:0000256|RuleBase:RU365051}.
