These H2AFY ELISA kits are immunodetection tools for measuring the levels of H2AFY in biological samples. H2AFY is an alias of the human MACROH2A1 gene, which encodes the protein, macroH2A.1 histone. Notably, H2AFY is known to play a role in DNA repair and the response to oxidative stress, among other functions. The MACROH2A1 protein is 369 amino acid residues in length and 39.2 kilodaltons in mass. However, as many as 3 protein isoforms have been identified. It is localized to the nucleus of the cell. In terms of tissue specificity, it is widely expressed across many tissue types. This protein is known to be ubiquitinated. Other names for this target antigen include H2A.y, H2A/y, and H2AF12M.
