||Abstract: "[Investigators] present the first reliable estimates of the total number of phosphoproteins and phosphorylation sites (p-sites), for four eukaryotes (human, mouse, Arabidopsis, and yeast)."
||P.4 left column 2nd paragraph: "Mouse is a mammal that is used extensively as a model for understanding human biology and is a rather close evolutionary relative of our own species with a time divergence of about 90 million years. Budding yeast, by comparison, is a unicellular fungus that diverged from its most-recent common ancestor with humans ∼1.3 billion years ago [primary source]. In addition, human and mouse have a very similar number of protein-coding genes, ∼20,000 [refs 30,31]."
