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. May act as a charged protein CC scaffold to promote snRNP assembly or strengthen snRNP-snRNP CC interactions through non-specific electrostatic contacts with RNA. CC {ECO:0000250|UniProtKB:P62314}. CC -!- SUBUNIT: Core component of the spliceosomal U1, U2, U4 and U5 small CC nuclear ribonucleoproteins (snRNPs), the building blocks of the CC spliceosome. Most spliceosomal snRNPs contain a common set of Sm CC proteins, SNRPB, SNRPD1, SNRPD2, SNRPD3, SNRPE, SNRPF and SNRPG that CC assemble in a heptameric protein ring on the Sm site of the small CC nuclear RNA to form the core snRNP. Component of the U1 snRNP. The U1 CC snRNP is composed of the U1 snRNA and the 7 core Sm proteins SNRPB, CC SNRPD1, SNRPD2, SNRPD3, SNRPE, SNRPF and SNRPG, and at least three U1 CC snRNP-specific proteins SNRNP70/U1-70K, SNRPA/U1-A and SNRPC/U1-C. CC Component of the U4/U6-U5 tri-snRNP complex composed of the U4, U6 and CC U5 snRNAs and at least PRPF3, PRPF4, PRPF6, PRPF8, PRPF31, SNRNP200, CC TXNL4A, SNRNP40, SNRPB, SNRPD1, SNRPD2, SNRPD3, SNRPE, SNRPF, SNRPG, CC DDX23, CD2BP2, PPIH, SNU13, EFTUD2, SART1 and USP39, plus LSM2, LSM3, CC LSM4, LSM5, LSM6, LSM7 and LSM8. Component of the minor spliceosome, CC which splices U12-type introns. Part of the SMN-Sm complex that CC contains SMN1, GEMIN2/SIP1, DDX20/GEMIN3, GEMIN4, GEMIN5, GEMIN6, CC GEMIN7, GEMIN8, STRAP/UNRIP and the Sm proteins SNRPB, SNRPD1, SNRPD2, CC SNRPD3, SNRPE, SNRPF and SNRPG; catalyzes core snRNPs assembly. Forms a CC 6S pICln-Sm complex composed of CLNS1A/pICln, SNRPD1, SNRPD2, SNRPE, CC SNRPF and SNRPG; ring-like structure where CLNS1A/pICln mimics CC additional Sm proteins and which is unable to assemble into the core CC snRNP. Interacts (via C-terminus) with SMN1 (via Tudor domain); the CC interaction is direct. Interacts with GEMIN2; the interaction is CC direct. Interacts with SNRPD2; the interaction is direct. CC {ECO:0000250|UniProtKB:P62314}. CC -!- SUBCELLULAR LOCATION: Cytoplasm, cytosol CC {ECO:0000250|UniProtKB:P62314}. Nucleus {ECO:0000250|UniProtKB:P62314}. 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:0000250|UniProtKB:P62314}. CC -!- PTM: Methylated on arginine residues by PRMT5 and PRMT7; probable CC asymmetric dimethylation which is required for assembly and biogenesis CC of snRNPs. {ECO:0000250|UniProtKB:P62314}. CC -!- SIMILARITY: Belongs to the snRNP core protein family. {ECO:0000305}.
