Figure 4From: Relationship between the tissue-specificity of mouse gene expression and the evolutionary origin and function of the proteinsExpression distribution of mouse protein functional groups. (a) The metabolic functional group includes enzymes and transporter proteins. (b) The regulatory group includes signal transduction and transcription regulation proteins. The pre-metazoa group includes universal proteins and eukaryote specific proteins. The metazoan-specific group includes metazoan-specific and mammalian-specific proteins. The plot presents the fraction of proteins in a group that are expressed in N tissues. The analysis is restricted to those proteins expressed in at least a single tissue. Sample size (number of assigned proteins): pre-metazoa metabolic proteins 1370; metazoan metabolic proteins 267, pre-metazoa regulatory proteins 169; metazoan regulatory proteins 493. The error bars indicate the standard error estimate using bootstrap resampling.Back to article page
