This entry represents the small nuclear ribonucleoprotein Sm D2 (Smd2) [PMID: 7527560]. Smd2 is a component of the SM core complex, a ring complex consists of six or seven subunits [PMID: 18687770]. SM complex associates with the snRNPs and is involved in the RNA-processing pathways [PMID: 18687770].

Small nuclear ribonucleoproteins (snRNPs) U1, U2, U4/U6 and U5 snRNPs play important roles in pre-mRNA splicing. The U1, U2, U4 and U5 small nuclear RNAs (snRNAs) present in these particles, each contains a conserved single-stranded sequence element, the Sm binding site. The Sm binding site interacts with the Sm proteins to form an Sm core structure [PMID: 18687770].
