The IAP3 ELISA kits listed below are analytical tools for measuring concentrations of IAP3 in various samples. IAP3 is an alternative name for the human XIAP gene, which encodes the protein, X-linked inhibitor of apoptosis. It has been mentioned that IAP3 plays a role in DNA damage pathways and the regulation of apoptosis, among other functions. Structurally, the XIAP protein is described to be 497 amino acid residues in length and 56.7 kilodaltons in mass. It is localized to the nucleus and cytoplasm of the cell. In terms of tissue specificity, it is reported to be expressed in colonic crypts. This protein is known to be ubiquitinated. Other names for this target antigen include API3, BIRC4, and IAP-3.
