CC       mediated assembly into core snRNPs occurs in the cytosol before SMN-
CC       mediated transport to the nucleus to be included in spliceosomes.
CC       {ECO:0000305}.
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:0000269|PubMed:11747828, ECO:0000269|PubMed:17709427}.
CC   -!- MISCELLANEOUS: In the autoimmune disease systemic lupus erythematosus,
CC       antinuclear antibodies are developed with Sm specificity.
CC   -!- SIMILARITY: Belongs to the snRNP core protein family. {ECO:0000305}.
