The CA15-3 ELISA kits listed below are analytical tools for measuring concentrations of CA15-3 in various samples. CA15-3 is an alternative name for the human MUC1 gene, which encodes the protein, mucin 1, cell surface associated. It has been mentioned that CA15-3 plays a role in DNA damage pathways and the regulation of apoptosis, among other functions. Structurally, the MUC1 protein is 1255 amino acid residues in length and 122.1 kilodaltons in mass. However, as many as 17 protein isoforms have been identified. It is localized to the cell membrane of the cell. In terms of tissue specificity, it is noted to be expressed on the apical surface of epithelial cells, especially of airway passages, breast and uterus. This protein is known to be O-glycosylated, N-glycosylated, palmitoylated, cleaved and phosphorylated. Other names for this target antigen include ADMCKD, ADMCKD1, and ADTKD2.
