H3K4me2 is a modification thought to have a role in transcriptional memory. In CD4+ T lymphocytes, H3K4Me2 is present within gene bodies regulating cellular function, but not in those of housekeeping genes, which indicates that the modification has a role in refining the tissue-specificity of expressed genes (PMID: 20841431). This type of cellular identity targeting is also noted in work with human and mouse spermatozoa (PMID: 20473313); the H3K4Me2 modification marks genes that are relevant in spermatogenesis. Most effects of H3K4Me2 seem to be attributed to its transcriptional activation; however, recent work also indicates that it may also play an RNA-dependent regressive role, related to the GAL-1 promoter (PMID: 19407817).

FAQs for Histone H3 Antibody (NB21-1022). (Showing 1 - 1 of 1 FAQ).

  1. The description says that this antibody react with C. elegans. Have it been tested in C elegans or is it just a prediction?
    • On our product page for our Histone H3 antibody with catalogue number NB21-1022, the western blot data was generated from C.elegans embryo lysate. This is the only C.elegans data that we currently have for this antibody, but if you would like to add your own data in the form of a product review you would be eligible for points which can be redeemed against a future purchase from Novus, or against an Amazon gift card.
