KMT2D is a large protein over 5,500 amino acids in size and is widely expressed in adult tissues.[6] The protein co-localizes with lineage determining transcription factors on transcriptional enhancers and is essential for cell differentiation and embryonic development.[5] It also plays critical roles in regulating cell fate transition,[5][7][8][9] metabolism,[10][11] and tumor suppression.[12][13][14][15]

Mutations in KMT2D have been associated with Kabuki syndrome,[16] congenital heart disease,[17] and various forms of cancer.[18]

Structure

Gene

In mice, KMT2D is coded by the Kmt2d gene located on chromosome 15F1. Its transcript is 19,823 base pairs long and contains 55 exons and 54 introns.[19] In humans, KMT2D is coded by the KMT2D gene located on chromosome 12q13.12. Its transcript is 19,419 base pairs long and contains 54 exons and 53 introns.[20]

Protein

KMT2D is homologous to Trithorax-related (Trr), which is a Trithorax-group protein.[21] The mouse and human KMT2D proteins are 5,588 and 5,537 amino acids in length, respectively. Both species of the protein weigh about 600 kDa.[19][20] KMT2D contains an enzymatically active C-terminal SET domain that is responsible for its methyltransferase activity and maintaining protein stability in cells.[22] Near the SET domain are a plant homeotic domain (PHD) and FY-rich N/C-terminal (FYRN and FYRC) domains. The protein also contains six N-terminal PHDs, a high mobility group (HMG-I), and nine nuclear receptor interacting motifs (LXXLLs).[18] It was shown that amino acids Y5426 and Y5512 are critical for the enzymatic activity of human KMT2D in vitro.[23] In addition, mutation of Y5477 in mouse KMT2D, which corresponds to Y5426 in human KMT2D, resulted in the inactivation of KMT2D's enzymatic activity in embryonic stem cells.[24] Depletion of cellular H3K4 methylation reduces KMT2D levels, indicating that the protein's stability could be regulated by cellular H3K4 methylation.[23]

Protein complex

Several components of the KMT2D complex were first purified in 2003,[25] and then the entire complex was identified in 2007.[26][27][28][29] Along with KMT2D, the complex also contains ASH2L, RbBP5, WDR5, DPY30, NCOA6, UTX (also known as KDM6A), PA1, and PTIP. WDR5, RbBP5, ASH2L, and DPY30 form the four-subunit sub-complex WRAD, which is critical for H3K4 methyltransferase activity in all mammalian Set1-like histone methyltransferase complexes.[30] WDR5 binds directly with FYRN/FYRC domains of C-terminal SET domain-containing fragments of human KMT2C and KMT2D.[26] UTX, the complex’s H3K27 demethylase, PTIP, and PA1 are subunits that are unique to KMT2C and KMT2D.[26][31][32] KMT2D acts as a scaffold protein within the complex; absence of KMT2D results in destabilization of UTX and collapse of the complex in cells.[5][23]

Enhancer regulation

KMT2D is a major enhancer mono-methyltransferase and has partial functional redundancy with KMT2C.[5][7] The protein selectively binds enhancer regions based on type of cell and stage of differentiation. During differentiation, lineage determining transcription factors recruit KMT2D to establish cell-type specific enhancers. For example, CCAAT/enhancer-binding protein β (C/EBPβ), an early adipogenic transcription factor, recruits and requires KMT2D to establish a subset of adipogenic enhancers during adipogenesis. Depletion of KMT2D prior to differentiation prevents the accumulation of H3K4 mono-methylation (H3K4me1), H3K27 acetylation, the transcriptional coactivator Mediator, and RNA polymerase II on enhancers, resulting in severe defects in gene expression and cell differentiation.[5] KMT2C and KMT2D also identify super-enhancers and are required for formation of super-enhancers during cell differentiation.[33] Mechanistically, KMT2C and KMT2D are required for the binding of H3K27 acetyltransferases CREB-binding protein (CBP) and/or p300 on enhancers, enhancer activation, and enhancer-promotor looping prior to gene transcription.[5][33] The KMT2C and KMT2D proteins, rather than the KMT2C and KMT2D-mediated H3K4me1, control p300 recruitment to enhancers, enhancer activation, and transcription from promoters in embryonic stem cells.[7]

Functions

Development

Whole-body knockout of Kmt2d in mice results in early embryonic lethality.[5] Targeted knockout of Kmt2d in precursors cells of brown adipocytes and myocytes results in decreases in brown adipose tissue and muscle mass in mice, indicating that KMT2D is required for adipose and muscle tissue development.[5] In the hearts of mice, a single copy of the Kmt2d gene is sufficient for normal heart development.[34] Complete loss of Kmt2d in cardiac precursors and myocardium leads to severe cardiac defects and early embryonic lethality. KMT2D mediated mono- and di-methylation is required for maintaining necessary gene expression programs during heart development. Knockout studies in mice also show that KMT2D is required for proper B-cell development.[12]

Cell fate transition

KMT2D is partially functionally redundant with KMT2C and is required for cell differentiation in culture.[5][7] KMT2D regulates the induction of adipogenic and myogenic genes and is required for cell-type specific gene expression during differentiation. KMT2C and KMT2D are essential for adipogenesis and myogenesis.[5] Similar functions are seen in neuronal and osteoblast differentiation.[8][9] KMT2D facilitates cell fate transition by priming enhancers (through H3K4me1) for p300-mediated activation. For p300 to bind the enhancer, the physical presence of KMT2D, and not just the KMT2D-mediated H3K4me1, is required. However, KMT2D is dispensable for maintaining embryonic stem cell and somatic cell identity.[7]

Metabolism

KMT2D is partially functionally redundant with KMT2C in the liver as well. Heterozygous Kmt2d^+/- mice exhibit enhanced glucose tolerance and insulin sensitivity and increased serum bile acid.[10] KMT2C and KMT2D are significant epigenetic regulators of the hepatic circadian clock and are co-activators of the circadian transcription factors retinoid-related orphan receptor (ROR)-α and -γ.[10] In mice, KMT2D also acts as a coactivator of PPARγ within the liver to direct over-nutrition induced steatosis. Heterozygous Kmt2d^+/- mice exhibit resistance to over-nutrition induced hepatic steatosis.[11]

Tumor suppression

KMT2C and KMT2D along with NCOA6 act as coactivators of p53, a well-established tumor suppressor and transcription factor, and are necessary for endogenous expression of p53 in response to doxorubicin, a DNA damaging agent.[13] KMT2C and KMT2D have also been implicated with tumor suppressor roles in acute myeloid leukemia, follicular lymphoma, and diffuse large B cell lymphoma.[12][14][15] Knockout of Kmt2d in mice negatively affects the expression of tumor suppressor genes TNFAIP3, SOCS3, and TNFRSF14.[15]

Conversely, KMT2D deficiency in several breast and colon cancer cell lines leads to reduced proliferation.[35][36][37] Increased KMT2D was shown to facilitate chromatin opening and recruitment of transcription factors, including estrogen receptor (ER), in ER-positive breast cancer cells.[38] Thus, KMT2D may have diverse effects on tumor suppression in different cell types.

Clinical significance

Loss of function mutations in KMT2D, also known as MLL2 in humans, have been identified in Kabuki syndrome,[16] with mutational occurrence rates between 56% and 75%.[39][40][41] Congenital heart disease has been associated with an excess of mutations in genes that regulate H3K4 methylation, including KMT2D.[17]

Frameshift and nonsense mutations in the SET and PHD domains affect 37% and 60%, respectively, of the total KMT2D mutations in cancers.[18] Cancers with somatic mutations in KMT2D occur most commonly in the brain, lymph nodes, blood, lungs, large intestine, and endometrium.[18] These cancers include medulloblastoma,[42][43][44] pheochromocytoma,[45] non-Hodgkin lymphomas,[46], cutaneous T-cell lymphoma, Sézary syndrome,[47] bladder, lung, and endometrial carcinomas,[48] esophageal squamous cell carcinoma,[49][50][51] pancreatic cancer,[52] and prostate cancer.[53]
