High impact information on smg-5

  • In smg-5, smg-6, and smg-7 mutants, a phosphorylated isoform of SMG-2 accumulated to abnormally high levels [1].
  • We describe a modified screen for smg mutations that precludes isolating alleles of smg-1, smg-2, and smg-5 [2].
 

Biological context of smg-5

  • In smg-2(r866) and smg-2(r895) mutants, which harbor single amino acid substitutions of the SMG-2 nucleotide binding site, phosphorylated SMG-2 accumulated to abnormally high levels, similar to those observed in smg-5, smg-6, and smg-7 mutants [1].
