Anti-NTN antibodies enable researchers to detect and measure the NTN antigen in biological samples. This target is a reported synonym of the NRTN gene, which encodes neurturin. This protein is known to function in MAPK cascade signaling pathways and nervous system development, among other biological roles. The human version of NTN has a canonical amino acid length of 197 residues and a protein mass of 22.4 kilodaltons. It is reported to be a secreted protein. NTN is a member of the TGF-beta protein family.
