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:Q9Y4Y9}.
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). LSM2, LSM3,
CC       LSM4, LSM5, LSM6, LSM7 and LSM8 form a heptameric, ring-shaped
CC       subcomplex (the LSM2-8 complex) that is part of the U4/U6-U5 tri-snRNP
CC       complex and the precatalytic spliceosome.
CC       {ECO:0000250|UniProtKB:Q9Y4Y9}.
CC   -!- SUBCELLULAR LOCATION: Nucleus {ECO:0000250|UniProtKB:Q9Y4Y9}.
CC   -!- SIMILARITY: Belongs to the snRNP Sm proteins family. {ECO:0000305}.
