Anti-BDB antibodies enable researchers to detect and measure the BDB antigen in biological samples. This target is a reported synonym of the ROR2 gene, which encodes receptor tyrosine kinase like orphan receptor 2. This protein is known to function in the regulation of cell migration and macrophage differentiation, among other biological roles. The human version of BDB has a canonical amino acid length of 943 residues and a protein mass of 104.8 kilodaltons. It is reported to be localized in the cell membrane of cells. Other names for this target antigen include BDB1 and NTRKR2.
