HELLS (helicase, lymphoid specific, also known as Lsh or SMARCA6) is a major epigenetic regulator crucial for normal heterochromatin structure and function. HELLS is part of the DEAD-like helicase superfamily, a diverse family of proteins involved in ATP-dependent RNA or DNA unwinding. This domain contains the ATP-binding region.
