The protein repertoire in early vertebrate embryogenesis

Summary We present an unprecedentedly comprehensive characterization of protein dynamics across early development in Xenopus laevis , available immediately via a convenient Web portal. This resource allows interrogation of the protein expression data in conjunction with other data modalities such as genome wide mRNA expression. This study provides detailed data for absolute levels of ∼14K unique Xenopus proteins representing homologues of ∼9K unique human genes – a rich resource for developmental biologists. The purpose of this manuscript is limited to presenting and releasing the data browser. Highlights Relative protein expression from stage IV oocyte, blastula, gastrula, neurula, and early organogenesis Biological triplicates with confidence intervals on protein expression reflect certainty in dynamic patterns Convenient time-series Web-browser integrated with the multi-media Xenbase portal Gene-symbol search and multi-gene protein/mRNA juxtaposition capabilities
