The acquisition of cytotoxic function by human CD4 T cells is an integral part of the T helper 1 differentiation pathway and is limited by the transcription factor ThPOK.
Gamete-derived three-amino-acid-loop-extension homeodomain proteins activate zygote development in a strikingly similar manner between basal land plants and green algae, indicating an ancestral role of these transcription factors in green plants.

The ancestral mechanism to activate diploid gene expression via homeodomain transcription factors was retained in liverworts, an early diverging land plant lineage, and subsequently co-opted during evolution of the diploid sporophyte body.

Analysis of the Arabidopsis V-ATPase reveals convergent evolution of differential targeting as well as redundancy of the endosomal and vacuolar isoforms during vegetative development.
