Kinome profile clustering of embryos ectopically expressing ERK2WT, ERK2 triple mutant, and FGF8. Simplified representation of FGF-ERK signalling pathways to downstream specific target clusters (up). Clusters are based on a Bionavigator-based clustering algorithm, which groups peptides into clusters according to treatment-based response similarities (down). AKT is Protein Kinase B (PKB), PLCγ is Phospholipase Cγ.
