a, Ribosome sedimentation analysis of Gapdh, 18S, 28S and Lnczc3h7a from peritoneal macrophages infected with VSV for 8 hr. Cell lysates were fractionated by sucrose gradient centrifugation. b, Prediction of putative proteins encoded by Lnczc3h7a (red rectangle) using ORF Finder (http://www.ncbi.nlm.nih.gov/orffinder/). c, The CSF scores of Lnczc3h7a determined by analysis with PhyloCSF. Data are representative of three independent experiments (a).
