We measured total proteomes of 15 different fission yeast strains : wild type, Δcid1, Δdis32, Δcid1Δdis32, Δlsm1, Δski2, Δcid1Δlsm1, Δdis32Δski2, Δcid1Δski2, Δcid1Δdis32Δski2, Δcid1Δdis32Δlsm1, Δdis32Δlsm1, Δlsm1Δski2, Δlsm1Δski2Δdis32, Δlsm1Δski2Δcid1. All mutantions affected cytoplasmic mRNA decay. At least 5 repeats were measured for each mutant.
