Description
Product Characteristics: HRX (Histone-lysine N-methyltransferase HRX) functions as histone methyltransferase. HRX methylates 'Lys-4' of histone H3. H3 'Lys-4' methylation represents a specific tag for epigenetic transcriptional activation. HRX promotes PPP1R15A-induced apoptosis. HRX interacts with SBF1 and PPP1R15A. HRX is a component of the MLL complex, at least composed of MLL, ASH2L, RBBP5, DPY30, WDR5, MEN1,HCFC1 and HCFC2. Chromosomal aberrations involving MLL are a cause of acute leukemias. A chromosomal aberration involving MLL may be a cause of chronic neutrophilic leukemia. HRX belongs to the histone-lysine methyltransferase family and TRX/MLL subfamily.
Synonyms: ALL1, CXXC7(CXXC-type zinc finger protein 7), HTRX, KMT2A, TRX1, MLL, Zinc finger protein HRX, Trithorax-like protein, Lysine N-methyltransferase 2A
Target Information: This 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. One of these domains, the SET domain, is responsible for its histone H3 lysine 4 (H3K4) methyltransferase activity which mediates chromatin modifications associated with epigenetic transcriptional activation. This protein is processed by the enzyme Taspase 1 into two fragments, MLL-C and MLL-N. These fragments reassociate and further assemble into different multiprotein complexes that regulate the transcription of specific target genes, including many of the HOX genes. Multiple chromosomal translocations involving this gene are the cause of certain acute lymphoid leukemias and acute myeloid leukemias. Alternate splicing results in multiple transcript variants.[provided by RefSeq, Oct 2010]
