High impact information on SMX3

  • Surprisingly, we observed that other evolutionarily conserved positions are tolerant to mutations, with substitutions affecting binding to SmF and SmG only mildly and conferring a wild-type growth phenotype [1].
  • To map the protein-protein interaction surface of Sm proteins, we generated a library of SmE mutants and investigated their ability to interact with SmF and/or SmG proteins in the two-hybrid system [1].
  • Formation of homo-oligomers by the spliceosomal small nuclear ribonucleoprotein components SmE and SmF preclude hetero-interactions vital to formation of functional small nuclear RNP complexes in vivo [2].
  • Homomeric ring assemblies of eukaryotic Sm proteins have affinity for both RNA and DNA. Crystal structure of an oligomeric complex of yeast SmF [2].
