Title:

Crystal structure of the trithorax group protein ASH2L reveals a forkhead-like DNA binding domain.

Journal:

Nat Struct Mol Biol. 2011 Jun 5;18(7):857-9. doi: 10.1038/nsmb.2093.

Abstract:

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.
