Anti-Nurr1 antibodies enable researchers to detect and measure the Nurr1 antigen in biological samples. This target is a reported synonym of the NR4A2 gene, which encodes nuclear receptor subfamily 4 group A member 2. This protein is known to function in the Wnt signaling pathway and the response to oxidative stress, among other biological roles. The human version of Nurr1 has a canonical amino acid length of 598 residues and a protein mass of 66.6 kilodaltons, although 2 isoforms have been identified. It is reported to be localized in the nucleus and cytoplasm of cells. Other names for this target antigen include HZF-3, IDLDP, and NOT. ELISA, Western Blot, and Immunohistochemistry are common applications for Nurr1 antibodies.
