What is the function of this protein?
Trithorax group (TrxG) protein that has histone methyltransferase activity (PubMed:13679578, PubMed:16882982).  Specifically trimethylates 'Lys-4' of histone H3 (H3K4me3), a specific tag for epigenetic transcriptional activation (PubMed:13679578, PubMed:16882982).  TrxG proteins are generally required to maintain the transcriptionally active state of homeotic genes throughout development.  Does not act as a coactivator required for transcriptional activation, but specifically prevents inappropriate Polycomb Group (PcG) silencing of homeotic genes in cells in which they must stay transcriptionally active (PubMed:15031712).
What are the official names of this protein?
Histone-lysine N-methyltransferase ash1, Absent small and homeotic disks protein 1, Lysine N-methyltransferase 2H.
What is the protein family that this protein belongs to?
Belongs to the class V-like SAM-binding methyltransferase superfamily. Histone-lysine methyltransferase family. SET2 subfamily.
What are the subcellular locations of this protein?
Nucleus. Chromosome. Note=Localizes at the promoter of active genes.
