Sm D2, L000004145, YLR275W
Core Sm protein Sm D2; part of heteroheptameric complex (with Smb1p, Smd1p, Smd3p, Sme1p, Smx3p, and Smx2p) that is part of the spliceosomal U1, U2, U4, and U5 snRNPs; homolog of human Sm D2

YPL157W
Trimethyl guanosine synthase, conserved nucleolar methyl transferase; converts the m(7)G cap structure of snRNAs, snoRNAs, and telomerase TLC1 RNA to m(2,2,7)G; also required for nucleolar assembly and splicing of meiotic pre-mRNAs; interacts with Swm2p, which may confer substrate specificity on Tgs1p

Synthetic Lethality

A genetic interaction is inferred when mutations or deletions in separate genes, each of which alone causes a minimal phenotype, result in lethality when combined in the same cell under a given condition.

Will the circle be unbroken: specific mutations in the yeast Sm protein ring expose a requirement for assembly factor Brr1, a homolog of Gemin2.

Schwer B, Roth AJ, Shuman S

A seven-subunit Sm protein ring assembles around specific U-rich RNA segments of the U1, U2, U4, and U5 snRNPs that direct pre-mRNA splicing. Using human snRNP crystal structures to guide mutagenesis in Saccharomyces cerevisiae, we gained new insights to structure-function relationships of the SmD1 and SmD2 subunits. Of sixteen conserved amino acids comprising their RNA-binding sites or inter-subunit interfaces, only ... [more]
