Function

[ASH2L_HUMAN] 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. As part of the MLL1/MLL complex it is involved in methylation and dimethylation at 'Lys-4' of histone H3. May function as a transcriptional regulator. May play a role in hematopoiesis.^[1] ^[2]

Publication Abstract from PubMed

Absent, small or homeotic discs-like 2 (ASH2L) is a trithorax group (TrxG) protein and a regulatory subunit of the SET1 family of lysine methyltransferases. Here we report that ASH2L binds DNA using a forkhead-like helix-wing-helix (HWH) domain. In vivo, the ASH2L HWH domain is required for binding to the beta-globin locus control region, histone H3 Lys4 (H3K4) trimethylation and maximal expression of the beta-globin gene (Hbb-1), validating the functional importance of the ASH2L DNA binding domain.

Crystal structure of the trithorax group protein ASH2L reveals a forkhead-like DNA binding domain.,Sarvan S, Avdic V, Tremblay V, Chaturvedi CP, Zhang P, Lanouette S, Blais A, Brunzelle JS, Brand M, Couture JF Nat Struct Mol Biol. 2011 Jun 5;18(7):857-9. doi: 10.1038/nsmb.2093. PMID:21642971^[3]
