2.7.11.24 ATP + a protein - 2.7.11.24 ATP + a protein MAPK activate mitogen-activated proteins in several signal transduction pathways, overview 2.7.11.24 ATP + activating transcription factor 2 ATF2 2.7.11.24 ATP + AP1 substrate of ERK1/2, ERK access to the substrate is regulated by the all-trans retinoic acid receptor, RAR 2.7.11.24 ATP + Arabidopsis thaliana protein AT1G7815 - 2.7.11.24 ATP + Arabidopsis thaliana protein AT2G26530 - 2.7.11.24 ATP + Arabidopsis thaliana protein AT3G11330 - 2.7.11.24 ATP + Arabidopsis thaliana protein AT4G38710 - 2.7.11.24 ATP + ATF2 - 2.7.11.24 ATP + BES1 i.e. brassinosteroid insensitive1-ethyl methanesulfonate-suppressor1, an Arabidospis thaliana transcription factor. S286 and S137 residues are required for flg22-induced BES1 full phosphorylation in vivo, in which S286 plays a greater role than S137
