To study this observation further, the protein interaction networks of S. cerevisiae and H. sapiens were analyzed taking into account an estimate for the age of the proteins in these species. These estimates were obtained by studying the presence and absence of putative orthologs in other eukaryotic species. In this work preliminary results are described that point to a dependence of the likelihood of protein interaction on the proteins’ age. The probability of two proteins interactions was found to be linearly dependent on the time the proteins have co-existed in the species. http://dx.doi.org/10.1038/npre.2007.22.1 Mon, 22 Jan 2007 16:50:37 UTC The likelihood that two proteins interact might depend on the proteins’ age doi:10.1038/npre.2007.22.1 2009-03-04 Pedro Beltrao Nature Precedings 2007-01-22T16:50:37Z Manuscript Bioinformatics Evolutionary Biology http://creativecommons.org/licenses/by/2.5/
