These ETX1 ELISA kits are immunodetection tools for measuring the levels of ETX1 in biological samples. ETX1 is an alias of the human SRPX gene, which encodes the protein, sushi repeat containing protein X-linked. Notably, ETX1 is known to play a role in autophagy pathways and cell adhesion, among other functions. The SRPX protein is 464 amino acid residues in length and 51.6 kilodaltons in mass. However, as many as 5 protein isoforms have been identified. It is localized to the cell membrane of the cell. In terms of tissue specificity, it is notably expressed in fibroblasts. This protein is known to be glycosylated. Other names for this target antigen include DRS.
