C21orf91 ELISA kits are immunoassay tools for the measurement of the protein chromosome 21 open reading frame 91, which is encoded by the C21orf91 gene in humans. Functionally, this protein is reported to play a role in in cortical progenitor cell proliferation and differentiation. The canonical protein structure is reported to have an amino acid length of 297 residues, a mass of 33.9 kDa, and is a member of the EURL protein family. It is notably expressed in the brain. As many as 3 protein isoforms have been reported. Other alias names for this target include C21orf14, C21orf38, CSSG1, EURL, YG81, protein EURL homolog, cold sore susceptibility gene 1, and BTG3-7:1.
