SETD2, also named as HIF1, HYPB, KIAA1732, KMT3A, SET2, p231HBP, hSET2 and HIP-1, belongs to the histone-lysine methyltransferase family and SET2 subfamily. SETD2 probably plays a role in chromatin structure modulation during elongation via its interaction with hyperphosphorylated POLR2A. It binds DNA at promoters. SETD2 may also act as a transcription activator that binds to promoters. It is a potential tumour suppressor gene in breast cancer. This antibody is specific to SETD2.
