Anti-Snep antibodies enable researchers to detect and measure the Snep antigen in biological samples. This target is a reported synonym of the SNED1 gene, which encodes sushi, nidogen and EGF like domains 1. This protein is known to function in cell matrix adhesion, among other biological roles. The human version of Snep has a canonical amino acid length of 1413 residues and a protein mass of 152.2 kilodaltons, although 4 isoforms have been identified. It is reported to be localized in the extracellular matrix and is secreted of cells. Other names for this target antigen include IRE-BP1 and SST3.
