CC   -!- FUNCTION: Plays role in pre-mRNA splicing as component of the U4/U6-U5
CC       tri-snRNP complex that is involved in spliceosome assembly, and as
CC       component of the precatalytic spliceosome (spliceosome B complex). The
CC       heptameric LSM2-8 complex binds specifically to the 3'-terminal U-tract
CC       of U6 snRNA. {ECO:0000250|UniProtKB:O95777}.
CC   -!- SUBUNIT: Component of the precatalytic spliceosome (spliceosome B
CC       complex). Component of the U4/U6-U5 tri-snRNP complex, a building block
CC       of the precatalytic spliceosome (spliceosome B complex). The U4/U6-U5
CC       tri-snRNP complex is composed of the U4, U6 and U5 snRNAs and at least
CC       PRPF3, PRPF4, PRPF6, PRPF8, PRPF31, SNRNP200, TXNL4A, SNRNP40, SNRPB,
CC       SNRPD1, SNRPD2, SNRPD3, SNRPE, SNRPF, SNRPG, DDX23, CD2BP2, PPIH,
CC       SNU13, EFTUD2, SART1 and USP39, plus LSM2, LSM3, LSM4, LSM5, LSM6, LSM7
CC       and LSM8. LSM2, LSM3, LSM4, LSM5, LSM6, LSM7 and LSM8 form a
CC       heptameric, ring-shaped subcomplex (the LSM2-8 complex) that is part of
CC       the U4/U6-U5 tri-snRNP complex and the precatalytic spliceosome.
CC       {ECO:0000250|UniProtKB:O95777}.
CC   -!- SUBCELLULAR LOCATION: Nucleus {ECO:0000250|UniProtKB:O95777}.
CC   -!- SIMILARITY: Belongs to the snRNP Sm proteins family. {ECO:0000305}.
CC   -!- SEQUENCE CAUTION:
CC       Sequence=ABE96774.2; Type=Erroneous initiation; Evidence={ECO:0000305};
