title: mRNA decay: x (XRN1) marks the spot.
abstract: Degradation of mRNA is a vital aspect of gene expression. In yeast, Dcp1p, Dcp2p, Lsm1-7p, and Xrn1p are required for mRNA decay and are localized within discrete cytoplasmic foci; in the May 2 issue of Science, Sheth and Parker provide compelling evidence that these foci represent sites for mRNA decay.
