Anti-DRAGON antibodies enable researchers to detect and measure the DRAGON antigen in biological samples. This target is a reported synonym of the RGMB gene, which encodes repulsive guidance molecule BMP co-receptor b. This protein is known to function in cell adhesion and the regulation of transcription, among other biological roles. The human version of DRAGON has a canonical amino acid length of 437 residues and a protein mass of 47.5 kilodaltons. It is reported to be localized in the cell membrane of cells. DRAGON is a member of the Repulsive guidance molecule (RGM) protein family.
