|Other Names||Histone-lysine N-methyltransferase mes-4, Maternal-effect sterile protein 4, mes-4|
|Target/Specificity||The synthetic peptide sequence used to generate the antibody AP1965c was selected from the Center region of human Mes-4. A 10 to 100 fold molar excess to antibody is recommended. Precise conditions should be optimized for a particular assay.|
|Format||The synthetic peptide was lyophilized with 100% acetonitrile and is supplied as a powder. Reconstitute with 0.1 ml deionized water for a final concentration of 1 mg/ml.|
|Storage||Maintain refrigerated at 2-8°C for up to 6 months. For long term storage store at -20°C.|
|Precautions||This product is for research use only. Not for use in diagnostic or therapeutic procedures.|
|Function||Histone methyltransferase. Dimethylates 'Lys-36' of histone H3, a specific tag for epigenetic transcriptional activation. Plays a central role in early development and is responsible for all H3 'Lys-36' dimethylation until about the 40- cell stage. Indirectly involved in the global inactivation of the X chromosomes in germline cells, possibly by excluding the mes-2- mes-3-mes-6 repressive Polycomb complex from the autosomes (PubMed:12077420, PubMed:16968818). Not related to transcription elongation (PubMed:12077420, PubMed:16968818). Required for small- RNA-induced H3K27 trimethylation (PubMed:26365259).|
|Cellular Location||Nucleus. Chromosome. Note=Specifically associated with the autosomes and with the distal tip of chromosome X. Colocalizes with methylated 'Lys-4' of histone H3|
|Tissue Location||In adults, it is predominantly expressed in the germline, and weakly expressed in intestinal cells|

Mes-4 is a histone methyltransferase. This protein dimethylates 'Lys-36' of histone H3, a specific tag for epigenetic transcriptional activation. Mes-4 plays a central role in early development and is responsible for all H3 'Lys-36' dimethylation until about the 40-cell stage. It appears to be indirectly involved in the global inactivation of the X chromosomes in germ line cells, possibly by excluding the mes-2-mes-3-mes-6 repressive Polycomb complex from the autosomes.
