Transcription is regulated by transcription factors (TFs) bound at enhancer elements located long-distances from the genes they regulate. How does this account for dynamic responses to the environment via signaling? Canonical views invoke signal induced changes in TF expression/modification or cofactor localization, but here we suggest that TF occupancy could be present before and after the signal, establishing competence, ensuring plasticity and blocking premature commitment. For ERK signaling, a central regulator of embryonic stem cell (ESC) differentiation, we found enhancers were regulated via selective recruitment of RNA Polymerase II (RNAPII) and associated cofactors. In this case,…
