Set1/Ash2 histone methyltransferase complex subunit ASH2 (ASH2L)

Component of the Set1/Ash2 histone methyltransferase (HMT) complex, a complex that specifically methylates'Lys-4' of histone H3, but not if the neighboring'Lys-9' residue is already methylated. Included in the MLL1/MLL complex it is involved in methylation and dimethylation in'Lys-4' of histone H3.

May function as a transcriptional regulator. May play a role in hematopoiesis.
