The LSM domain contains Sm proteins as well as other related LSM (Like Sm) proteins. The U1, U2, U4/U6, and U5 small nuclear ribonucleoprotein particles (snRNPs) involved in pre-mRNA splicing contain seven Sm proteins (B/B', D1, D2, D3, E, F and G) in common, which assemble around the Sm site present in four of the major spliceosomal small nuclear RNAs. The U6 snRNP binds to the LSM (Like Sm) proteins [3]. Sm proteins are also found in archaebacteria, which do not have any splicing apparatus suggesting a more general role for Sm proteins. All Sm proteins contain a common sequence motif in two segments, Sm1 and Sm2, separated by a short variable linker. This family also includes the bacterial Hfq (host factor Q) proteins. Hfq are also RNA-binding proteins, that form hexameric rings.	Domain

Yeast Spp2, a G-patch protein and spliceosome component, interacts with the ATP-dependent DExH-box splicing factor Prp2 [1]. As this interaction involves the G-patch sequence in Spp2 and is required for the recruitment of Prp2 to the spliceosome before the first catalytic step of splicing, it is proposed that Spp2 might be an accessory factor that confers spliceosome specificity on Prp2 [2].
