These XAP1 ELISA kits are immunodetection tools for measuring the levels of XAP1 in biological samples. XAP1 is an alias of the human DDB1 gene, which encodes the protein, damage specific DNA binding protein 1. Notably, XAP1 is known to play a role in the apoptotic pathway and DNA damage pathways, among other functions. The DDB1 protein is 1140 amino acid residues in length and 127 kilodaltons in mass. However, as many as 2 protein isoforms have been identified. It is localized to the nucleus and cytoplasm of the cell. This protein is known to be ubiquitinated, acetylated, cleaved and phosphorylated. Other names for this target antigen include DDBA, UV-DDB1, and WHIKERS.
