The ELISA kits listed below target DDR1, the symbol for the human gene, discoidin domain receptor tyrosine kinase 1, and a member of the Protein kinase superfamily, Tyr protein kinase family, Insulin receptor subfamily. The protein has an enzyme classification of receptor protein-tyrosine kinase. The protein encoded by DDR1 has a predicted amino acid length of 913, a mass of 101.1 kDa, and a membrane and secreted subcellular localization. There are currently 5 reported isoforms, as well as sites of glycosylation. DDR1 may also be known by the following names: neurotrophic tyrosine kinase receptor type 4, neuroepithelial tyrosine kinase, cell adhesion kinase, PTK3A protein tyrosine kinase 3A, CD167 antigen-like family member A, and epithelial discoidin domain-containing receptor 1, and tyrosine kinase DDR. Orthologs of the gene, including human, mouse, rat, and other mammalian are available targets of several ELISA kits.
