Research suggests that the histone methyltransferase Setd2 plays a crucial role in V(D)J recombination. Setd2 is also involved in various other biological processes, including the regulation of inflammatory states, immune cell function, and epigenetic programming. The specific mechanisms and effects of Setd2 in these contexts are being explored in different studies, with some focusing on its role in hematopoietic cells, immune regulation, and disease.
