KMT2D is a major mammalian H3K4 mono-methyltransferase; its C-terminal SET domain is responsible for H3K4 methyltransferase activity and is necessary for maintaining KMT2D protein stability in cells. KMT2D associates with WRAD (WDR5, RbBP5, ASH2L, DPY30), NCOA6, PTIP, PA1, and H3K27 demethylase UTX in one protein complex, acting as a scaffold that maintains UTX stability. KMT2D co-localizes with lineage-determining transcription factors on transcriptional enhancers and is required for binding of histone H3K27 acetyltransferases CBP and p300 on enhancers. |

AKT (downstream of PI3Kα) binds and phosphorylates KMT2D, attenuating its methyltransferase activity and ER-dependent transcription. PI3Kα inhibition enhances KMT2D activity and mediates an open chromatin state at ER target loci. KMT2D is required for FOXA1, PBX1, and ER recruitment and activation at these loci. |

The RBP-J interacting factor SHARP interacts with both the NCoR corepressor complex and the KMT2D coactivator complex; KMT2D and NCoR compete for the C-terminal SPOC domain of SHARP. The SPOC domain exclusively binds phosphorylated NCoR, and the balance is shifted by mutating NCoR phosphorylation sites or inhibiting the NCoR kinase CK2β. Drosophila homologs of SHARP and KMT2D also physically interact and control Notch-mediated functions in vivo. |
