MLL1 is a histone methyltransferase deemed a positive global regulator of gene transcription. This protein belongs to the group of histone-modifying enzymes comprising transactivation domain 9aaTAD and is involved in the epigenetic maintenance of transcriptional memory.
Its role as an epigenetic regulator of neuronal function is an ongoing area of research. KMT2A gene encodes a transcriptional coactivator that plays an essential role in regulating gene expression during early development and hematopoiesis. The encoded protein contains multiple conserved functional domains. It also upregulates mono- and dimethylation of H3K4.
These fragments then assemble into different multi-protein complexes that regulate the transcription of specific target genes, including many of the HOX genes. Transcriptome profiling after deletion of MLL1 in cortical neurons revealed decreased promoter-bound H3K4me3 peaks at 318 genes, with 31 of these having significantly decreased expression and promoter binding. Among them were Meis2, a homeobox transcription factor critical for development of forebrain neurons and Satb2, a protein involved in neuronal differentiation. Multiple chromosomal translocations involving this gene are the cause of certain acute lymphoid leukemias and acute myeloid leukemias.
