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.

In plants, ICln induces Cl- currents [1,4,5], thus regulating Cl- homoeostasis in eukaryotes [2,3]. Structurally, the fold resembles a pleckstrin homology fold, on of whose roles is to recruit and tether their host protein to the cell membrane; and although the surface charges of the ICln fold are not equivalent to those of the PH domain, ICln can be phosphorylated in vitro and the PH-nature of the domain may be the part involving it in the transposition from cytosol to cell membrane during cytotonic swelling [1].
