Cellular differentiation decisions, such as fates of B cells following entry into the germinal centres, are governed by epigenetically and transcriptionally regulated paths for bifurcating cell fates. Here the authors show that CFP1 is a master epigenetic regulator of activated B cells and controls their hypermutation and affinity maturation via the histone methyltransferase complex Setd1A/B.
