Supplier Data

Western blot - Anti-KMT2A / MLL antibody [EPR22647-8] - BSA and Azide free (AB256550)

Blocking and Dilution Buffer and concentration : 5% NFDM/TBST.

The molecular weight observed is consistent with what has been described in the literature (PMID : 12482972). This antibody reacts with unidentifiable proteins below 315 kDa. ab234435 was shown to specifically react with KMT2A/MLL in wild-type HAP1 cells as signal was lost in KMT2A/MLL knockout cells. Wild-type and KMT2A/MLL knockout samples were subjected to SDS-PAGE. ab234435 and ab181602 (Rabbit anti-GAPDH loading control) were incubated 1 hour at room temperature at 1/1000 dilution and 1/200,000 dilution respectively. Blots were developed with Goat Anti-Rabbit IgG, (H+L), Peroxidase conjugated (ab97051) secondary antibody at 1/100,000 dilution for 1 hour at room temperature before imaging. The blot was developed on a BIO-RAD^® ChemiDoc™ MP instrument using the ECL technique.

Exposure time : 48 seconds

This data was developed using the same antibody clone in a different buffer formulation containing PBS, BSA, glycerol, and sodium azide (ab234435).

Supplementary information

The KMT2A protein also known as MLL (Mixed-Lineage Leukemia) is a large protein with a molecular weight of approximately 431 kDa. This protein functions as a histone methyltransferase which means it adds methyl groups to histone proteins specifically at the lysine 4 position on histone H3 (H3K4). This modification impacts chromatin structure and gene expression. KMT2A/MLL is chiefly expressed in hematopoietic stem cells and various tissue types indicating its broad role in regulation across the body. The protein features a SET domain a characteristic motif for proteins involved in chromatin modification.

Biological function summary

This methyltransferase plays a significant role in regulating gene expression required for normal hematopoietic development and maintenance. KMT2A/MLL forms part of the multi-protein complex called COMPASS-like complex which is essential for its function in methylation activity. Within this complex it associates with other proteins like WDR5 RBBP5 and ASH2L that collaborate to control transcriptional elongation. KMT2A/MLL is also involved in maintaining the expression of various homeobox (HOX) genes which are critical for embryonic development and cell differentiation.

Pathways

KMT2A/MLL plays an integral role in hematopoietic and developmental signaling pathways. One key pathway is the Wnt signaling pathway important for regulating stem cell pluripotency and cell fate decisions. Another pathway is the Notch signaling pathway important for cell differentiation processes. KMT2A interacts with proteins within these pathways such as CXXC1 which links it to the DNA binding properties required for regulating target gene expression.

KMT2A/MLL is closely linked to leukemia notably acute lymphoblastic leukemia (ALL) and acute myeloid leukemia (AML). A significant factor contributing to these associations is the gene fusions involving KMT2A often created during chromosomal translocations which result in oncogenic activation. In these leukemias it can form fusion proteins like MLL-AF4 impacting the normal regulatory activities of KMT2A. This aberrant interaction with proteins such as MEN1 can contribute to oncogenic processes by altering transcription and leading to uncontrolled cell growth.

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).
