Figure 3.
Empirical density distribution of log2 fold changes (ratio of means) for GPCRs, ion channels, RKs, and non-RK kinases in human (A) and mouse (B). RKs and kinases as a group are weakly de-enriched in human and weakly enriched in mouse cultures (in the context of mean expression). However, both GPCRs and ion channels are strongly de-enriched in both human and mouse cultures, likely because of the variety of these genes that are expressed in sensory neurons.
