Histone methyltransferase. Specifically methylates 'Lys- 4' of histone H3, inducing di- and tri-methylation, but not monomethylation. Plays an important role in transcriptional activation as a member of an RNA polymerase complex. Binds DNA containing 5'-CCCTCC-3' or 5'-GAGGGG-3' sequences. Belongs to the histone-lysine methyltransferase family. 3 isoforms of the human protein are produced by alternative splicing. Note: This description may include information from UniProtKB.
