Product Usage Information

Storage: Supplied in 10 mM sodium HEPES (pH 7.5), 150 mM NaCl, 100 µg/ml BSA and 50% glycerol. Store at –20°C. Do not aliquot the antibody.

Specificity / Sensitivity

MORF4L1/MRG15 Antibody recognizes endogenous levels of total MORF4L1/MRG15 protein. This antibody does not cross-react with MORF4L2/MRGX.


Species predicted to react based on 100% sequence homology: Hamster, Bovine, Dog, Guinea Pig, Horse

Source / Purification

Polyclonal antibodies are produced by immunizing animals with a synthetic peptide corresponding to residues surrounding Ala237 of human MORF4L1/MRG15 protein. Antibodies are purified by protein A and peptide affinity chromatography.

Mortality factor 4-like protein 1 (MORF4L1/MRG15) is a chromo domain-containing protein that is part of several histone modifying complexes, including the Tip60 histone acetyltransferase (HAT) complex, histone deacetylase (HDAC) complexes, and the JARID1A and JARID1B histone demethylase complexes (1-6). MORF4L1/MRG15 recognizes di- or trimethylated Lys36 of histone H3 through its chromo domain. This interaction recruits and anchors MORF4L1/MRG15-associated chromatin modifying complexes to target genes for transcriptional regulation (7,8). MORF4L1/MRG15 plays a role in DNA repair as part of the Tip60 HAT complex (9,10). MORF4L1/MRG15 regulates alternative splicing during co-transcriptional splicing of mRNA as a part of the JARID1A complex (11). MORF4L1/MRG15 recruitment of the JARID1B complex to embryonic stem cell renewal-associated genes is important for repression of cryptic transcription and maintenance of proper transcriptional elongation (6).
