Anti-KMT2A / MLL + KMT2B / MLL4 antibody [EPR28282-16] - C-terminal,Abcam,AB315464

Target data Histone methyltransferase that plays an essential role in early development and hematopoiesis (PubMed : 12453419, PubMed : 15960975, PubMed : 19187761, PubMed : 19556245, PubMed : 20677832, PubMed : 21220120, PubMed : 26886794). 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) (PubMed : 12453419, PubMed : 15960975, PubMed : 19187761, PubMed : 19556245, PubMed : 20677832, PubMed : 21220120, PubMed : 24235145, PubMed : 26886794). 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 (PubMed : 12453419, PubMed : 15960975, PubMed : 19187761, PubMed : 19556245, PubMed : 20677832, PubMed : 21220120, PubMed : 25561738, PubMed : 26886794). Has weak methyltransferase activity by itself, and requires other component of the MLL1/MLL complex to obtain full methyltransferase activity (PubMed : 19187761, PubMed : 26886794). 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' (PubMed : 19187761). Binds to unmethylated CpG elements in the promoter of target genes and helps maintain them in the nonmethylated state (PubMed : 20010842). Required for transcriptional activation of HOXA9 (PubMed : 12453419, PubMed : 20010842, PubMed : 20677832). Promotes PPP1R15A-induced apoptosis (PubMed : 10490642). Plays a critical role in the control of circadian gene expression and is essential for the transcriptional activation mediated by the CLOCK-BMAL1 heterodimer (By similarity). 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 (By similarity). Also has auto-methylation activity on Cys-3882 in absence of histone H3 substrate (PubMed : 24235145). See full target information KMT2A Additional targets KMT2B
