Anti-EURL antibodies enable researchers to detect and measure the EURL antigen in biological samples. This target is a reported synonym of the C21orf91 gene, which encodes chromosome 21 open reading frame 91. This protein is known to function in neuronal differentiation, among other biological roles. The human version of EURL has a canonical amino acid length of 297 residues and a protein mass of 33.9 kilodaltons, although 3 isoforms have been identified. It is reported to be widely expressed in many tissue types. EURL is a member of the EURL protein family.
