function
FUNCTION: Histone methyltransferase that plays an essential role in early development and hematopoiesis (By similarity). Catalytic subunit of the MLL1/MLL complex, a multiprotein complex that mediates both methylation of 'Lys-4' of histone H3 (H3K4me) complex and acetylation of 'Lys-16' of histone H4 (H4K16ac) (By similarity). Catalyzes methyl group transfer from S-adenosyl-L-methionine to the epsilon-amino group of 'Lys-4' of histone H3 (H3K4) via a non-processive mechanism. Part of chromatin remodeling machinery predominantly forms H3K4me1 and H3K4me2 methylation marks at active chromatin sites where transcription and DNA repair take place (By similarity). Has weak methyltransferase activity by itself, and requires other component of the MLL1/MLL complex to obtain full methyltransferase activity (By similarity). Has no activity toward histone H3 phosphorylated on 'Thr-3', less activity toward H3 dimethylated on 'Arg-8' or 'Lys-9', while it has higher activity toward H3 acetylated on 'Lys-9' (By similarity). Binds to unmethylated CpG elements in the promoter of target genes and helps maintain them in the nonmethylated state (By similarity). Required for transcriptional activation of HOXA9 (By similarity). Promotes PPP1R15A-induced apoptosis (By similarity). Plays a critical role in the control of circadian gene expression and is essential for the transcriptional activation mediated by the CLOCK-BMAL1 heterodimer (PubMed:21113167). Establishes a permissive chromatin state for circadian transcription by mediating a rhythmic methylation of 'Lys-4' of histone H3 (H3K4me) and this histone modification directs the circadian acetylation at H3K9 and H3K14 allowing the recruitment of CLOCK-BMAL1 to chromatin (PubMed:21113167). Also has auto-methylation activity on Cys-3879 in absence of histone H3 substrate (By similarity). {ECO:0000250|UniProtKB:Q03164, ECO:0000269|PubMed:21113167}.

post_translational_modification
PTM: Proteolytic cleavage by TASP1 generates MLL cleavage 3product N320 and MLL cleavage product C180, which reassemble through a non-covalent association. 2 cleavage sites exist, cleavage site 1 (CS1) and cleavage site 2 (CS2), to generate MLL cleavage products N320 and C180. CS2 is the major site. {ECO:0000250|UniProtKB:Q03164}.; PTM: Phosphorylation increases its interaction with PSIP1. {ECO:0000250|UniProtKB:Q03164}.; PTM: Auto-methylated at Cys-3879: auto-methylation is inhibited by the WRAD complex and unmodified histone H3. {ECO:0000250|UniProtKB:Q03164}.
