  • a bipartite nuclear localization signal (NLS)
  • a PHD type (C4-H-C3) zinc finger domain
  • an atypical PHD finger that does not have histone tail-binding activity
  • a forkhead-like helix-wing-helix (HWH) domain, 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)
  • a zinc finger motif (C2C2) although it is not identical to that in ASH2
  • a highly conserved SPRY domain required for the intrinsic histone methyltransferase activity
  • mono polymer heteromer , dimer
    interspecies homolog to drosophila Ash2
    CATEGORY transcription factor
    SUBCELLULAR LOCALIZATION     intracellular
    basic FUNCTION
  • maintaining chromatin in a transcriptionally active information
  • plays a role in hematopoiesis and is associated with some special kinds of leukemia
  • core component of a multimeric histone methyltransferase complex that epigenetically regulates transcription via methylation of histone lysine residues
  • has a role in chromosome demarcation
  • key regulator of open chromatin in ES cells
  • importance of ASH2L in open chromatin regulation
  • is required for ES cell pluripotency and the global, active chromatin modifications associated with ES cells
  • CELLULAR PROCESS nucleotide, transcription
    a component
  • component of the SETD1A complex, including CCNY, RBBP5, ASH2L, WDR5, and WDR82, associating with SETD1B (COMPASS complex)
  • part of a CHD8/WDR5/ASH2L/RBBP5 complex
  • novel component of the Xi (inactive X chromosome)
  • heterodimer of ASH2L and RBBP5 has intrinsic histone methyltransferase activity
  • core component of the MLL family histone methyltransferases and has an important role in regulating the methylation of histone H3 on lysine 4
    DNA binds DNA using a forkhead-like helix-wing-helix (HWH) domain
    small molecule
  • positively mediates TFAP2D transactivation in a dose-dependent manner
  • FGFR3 is a transcriptional target of TFAP2D and ASH2L-containing histone methyltransferase complexes
  • recruited by XIST concomitantly with HNRNPU and macroH2A at the transition to inactive X chromosome maintenance
  • ASH2L/RBBP5 heterodimer stimulates the MLL1 methyltransferase activity through coordinated substrate interactions with the MLL1 SET domain
  • physical interaction between TBX1 and ASH2L suggesting that at least some functions of TBX1 may be mediated by direct interactions with a histone methyltransferase complex
  • can bind DNA and may function as a DNA-binding factor itself to directly recruit MLL complex to modify histones
  • molecular link between CHD7 and KMT2D function likely via their known interaction with members of the WAR complex (WDR5, ASH2L, RBBP5) which has been shown to be involved in histone methylation
