SUSD4 ELISA kits are immunoassay tools for the measurement of the protein sushi domain containing 4, which is encoded by the SUSD4 gene in humans. Functionally, this protein is known to act as complement inhibitor by disrupting the formation of the classical C3 convertase. The canonical protein structure is reported to have an amino acid sequence of 490 residues and a mass of 53.8 kDa. It is known to be secreted. As many as 4 protein isoforms have been reported. The protein has been noted to be post-translationally glycosylated. Other alias names for this target include sushi domain-containing protein 4, YHGM196, testicular secretory protein Li 55, and PRO222.
