Fig. 7From: A novel nuclear receptor subfamily enlightens the origin of heterodimerizationThe evolution of dimerization and class I/II markers across the whole NR superfamily. A Successive states of class I/II markers evolution. B Phylogeny of NRs with the main steps in the acquisition of RXR-heterodimerization indicated. The arrows between the two panels link the state of class I/II markers with the NR diversificationBack to article page
