CC -!- FUNCTION: Component of LSm protein complexes, which are involved in RNA
CC processing and may function in a chaperone-like manner, facilitating
CC the efficient association of RNA processing factors with their
CC substrates. Component of the cytoplasmic LSM1-LSM7 complex, which is
CC thought to be involved in mRNA degradation by activating the decapping
CC step in the 5'-to-3' mRNA decay pathway. Component of the nuclear LSM2-
CC LSM8 complex, which is involved in splicing of nuclear mRNAs. LSM2-LSM8
CC associates with multiple snRNP complexes containing the U6 snRNA (U4/U6
CC di-snRNP, spliceosomal U4/U6.U5 tri-snRNP, and free U6 snRNP). It binds
CC directly to the 3'-terminal U-tract of U6 snRNA and plays a role in the
CC biogenesis and stability of the U6 snRNP and U4/U6 snRNP complexes.
CC LSM2-LSM8 probably also is involved degradation of nuclear pre-mRNA by
CC targeting them for decapping, and in processing of pre-tRNAs, pre-rRNAs
CC and U3 snoRNA (By similarity). {ECO:0000250}.
CC -!- SUBUNIT: Component of the heptameric LSM1-LSM7 complex, which consists
CC of LSM1, LSM2, LSM3, LSM4, LSM5, LSM6 and LSM7. Component of the
CC heptameric LSM2-LSM8 complex, which consists of LSM2, LSM3, LSM4, LSM5,
CC LSM6, LSM7 and LSM8. The LSm subunits form a seven-membered ring
CC structure with a doughnut shape (By similarity). {ECO:0000250}.
CC -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000250}. Nucleus {ECO:0000250}.
CC -!- SIMILARITY: Belongs to the snRNP Sm proteins family. SmF/LSm6
CC subfamily. {ECO:0000305}.
