SETD2 protein is a
histone methyltransferase that is specific for lysine-36 of
histone H3, and methylation of this residue is associated with active
chromatin. This protein also contains a novel transcriptional activation domain and has been found associated with hyperphosphorylated
RNA polymerase II. Depletion of SETD2 increases the frequency of
deletion mutations that arise by the alternative
DNA repair process of
microhomology-mediated end joining. == Clinical significance ==
