Related Product Information for anti-DOT1L antibody
Similar to acetylation and phosphorylation, histone methylation at the N-terminal tail has emerged as an important role in regulating chromatin dynamics and gene activity. Histone methylation occurs on arginine and lysine residues and is catalyzed by two families of proteins, the protein arginine methyltransferase family and the SET-domain-containing methyltransferase family. Five members have been identified in the arginine methyltransferase family. About 27 are grouped into the SET-domain family, and another 17 make up the PR domain family that is related to the SET domain family. The retinoblastoma protein-interacting zinc finger geneRIZ1 is a tumor suppressor gene and a FOUNDING member of the PR domain family. RIZ1 inactivation is commonly found in many types of human cancers and occurs through loss of mRNA expression, frame shift mutation, chromosomal deletion, and missense mutation. RIZ1 is also a tumor susceptibility gene in mice. The loss of RIZ1 mRNA in human cancers was shown to associate with DNA methylation of its promoter CpG island. Methylation of the RIZ1 promoter strongly correlated with lost or decreased RIZ1 mRNA expression in breast, liver, colon, and lung cancer cell lines as well as in liver cancer tissues.

NCBI Description

The protein encoded by this gene is a histone methyltransferase that methylates lysine-79 of histone H3. It is inactive against free core histones, but shows significant histone methyltransferase activity against nucleosomes. [provided by RefSeq, Aug 2011]

Uniprot Description

DOT1L: a protein methyltransferase that catalyzes the mono-, di- and tri-methylation of H3K79. Methylated H3K79 is associated with active gene transcription. DOT1L activity drives proliferation of mixed lineage leukemia 1 protein (MLL)-rearranged leukemias, inducing the aberrant transcription of a number of leukemogenic genes including HOXA9 and MEIS1. Binds to DNA. Belongs to the class I-like SAM-binding methyltransferase superfamily. DOT1 family. 2 isoforms of the human protein are produced by alternative splicing.

Protein type: Methyltransferase; Amino Acid Metabolism - lysine degradation; EC 2.1.1.43; Methyltransferase, protein lysine

Chromosomal Location of Human Ortholog: 19p13.3

Cellular Component: nucleus

Molecular Function: protein binding; DNA binding; histone lysine N-methyltransferase activity (H3-K79 specific); histone-lysine N-methyltransferase activity; transcription factor binding

Biological Process: regulation of JAK-STAT cascade; regulation of cell cycle; chromatin silencing

Product Notes

The DOT1L dot1l (Catalog #AAA9200785) is an Antibody produced from Rabbit and is intended for research purposes only. The product is available for immediate purchase. The immunogen sequence is 1390-1420. The KMT4 / Dot1L Antibody (C-Term) reacts with Human and may cross-react with other species as described in the data sheet. AAA Biotech's KMT4 / Dot1L can be used in a range of immunoassay formats including, but not limited to, ELISA (EIA), Immunohistochemistry (IHC). IHC-P~~1:50~100. Researchers should empirically determine the suitability of the DOT1L dot1l for an application not listed in the data sheet. Researchers commonly develop new applications and it is an integral, important part of the investigative research process. It is sometimes possible for the material contained within the vial of "KMT4 / Dot1L, Polyclonal Antibody" to become dispersed throughout the inside of the vial, particularly around the seal of said vial, during shipment and storage. We always suggest centrifuging these vials to consolidate all of the liquid away from the lid and to the bottom of the vial prior to opening. Please be advised that certain products may require dry ice for shipping and that, if this is the case, an additional dry ice fee may also be required.
