CC -!- FUNCTION: Component of LSM protein complexes, which are involved in RNA
CC processing. Component of the cytoplasmic LSM1-LSM7 complex which is
CC involved in mRNA degradation by promoting decapping and leading to
CC accurate 5'-3' mRNA decay. The cytoplasmic LSM1-LSM7 complex regulates
CC developmental gene expression by the decapping of specific development-
CC related transcripts. Component of the nuclear LSM2-LSM8 complex which
CC is involved splicing nuclear mRNAs. LSM2-LSM8 binds directly to the U6
CC small nuclear RNAs (snRNAs) and is essential for accurate splicing of
CC selected development-related mRNAs through the stabilization of the
CC spliceosomal U6 snRNA. Plays a critical role in the regulation of
CC development-related gene expression. {ECO:0000269|PubMed:23221597,
CC ECO:0000269|PubMed:23620288}.
CC -!- SUBUNIT: Component of the heptameric LSM1-LSM7 complex that forms a
CC seven-membered ring structure with a donut shape. The LSM subunits are
CC arranged in the order LSM1, LSM2, LSM3, LSM6, LSM5, LSM7 and LSM4.
CC Component of the heptameric LSM2-LSM8 complex that forms a seven-
CC membered ring structure with a donut shape. The LSM subunits are
CC arranged in the order LSM8, LSM2, LSM3, LSM6, LSM5, LSM7 and LSM4
CC (PubMed:23221597, PubMed:23620288). LSM6B subunit interacts only with
CC its two neighboring subunits, LSM3A or LSM3B and LSM5
CC (PubMed:23221597). {ECO:0000269|PubMed:23221597,
CC ECO:0000269|PubMed:23620288}.
CC -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000269|PubMed:23221597}. Nucleus
CC {ECO:0000269|PubMed:23221597}.
CC -!- TISSUE SPECIFICITY: Expressed in roots, leaves, stems, flowers and
CC siliques. {ECO:0000269|PubMed:23221597, ECO:0000269|PubMed:23620288}.
CC -!- SIMILARITY: Belongs to the snRNP Sm proteins family. {ECO:0000305}.
