Anti-ARA antibodies enable researchers to detect and measure the ARA antigen in biological samples. This target is a reported synonym of the FOXC1 gene, which encodes forkhead box C1. This protein is known to function in the morphogenesis of anatomical structure and angiogenesis, among other biological roles. The human version of ARA has a canonical amino acid length of 553 residues and a protein mass of 56.8 kilodaltons. It is reported to be localized in the nucleus of cells.
