Anti-KRM2 antibodies enable researchers to detect and measure the KRM2 antigen in biological samples. This target is a reported synonym of the KREMEN2 gene, which encodes kringle containing transmembrane protein 2. This protein is known to function in limb development and the Wnt signaling pathway, among other biological roles. The human version of KRM2 has a canonical amino acid length of 462 residues and a protein mass of 48.8 kilodaltons, although 6 isoforms have been identified. It is reported to be localized in the membrane of cells.
