Anti-GRAM domain containing 3 antibodies enable researchers to detect and measure the GRAM domain containing 3 antigen in biological samples. This target is a reported synonym of the GRAMD2B gene, which encodes GRAM domain containing 2B. The human version of GRAM domain containing 3 has a canonical amino acid length of 432 residues and a protein mass of 47.9 kilodaltons, although 5 isoforms have been identified. It is reported to be widely expressed in many tissue types. Other names for this target antigen include GRAM domain-containing protein 2B and GRAM domain containing 3.
