Figure 2. — Proposed contributions of membrane proteins to the evolution of nuclear structure. Different types of proteins are proposed to have contributed to the incremental evolution of nuclear structure including soluble proto-coatomer proteins (aqua), DNA- or chromatin-binding membrane proteins (navy blue), centromere- or par system–associated membrane proteins (light purple), homotypic membrane “adhesion” proteins (yellow), and heterotypic membrane adhesion proteins (teal and light green). Blue indicates partitioning proteins (actin, ATPase, DNA-binding coiled-coil protein, tubulin), many of which are components of the nucleoskeleton in living Opisthokonts (see text).
