Anti-EDDR1 antibodies are used in antigen-specific immunodetection in biological samples. The target EDDR1 is a known alias name of the protein discoidin domain receptor tyrosine kinase 1, encoded by the DDR1 gene in humans. This 913-amino acid residue protein is reported to be a tyrosine kinase that functions as cell surface receptor for fibrillar collagen and regulates cell attachment to the extracellular matrix, remodeling of the extracellular matrix, cell migration, differentiation, survival and cell proliferation. It is localized to the cell membrane and is secreted of the cell and features glycosylated and phosphorylated post-translational modifications. In terms of tissue expression, it is notably expressed in T-47D, MDA-MB-175 and HBL-100 breast carcinoma cells, A-431 epidermoid carcinoma cells, SW48 and SNU-C2B colon carcinoma cells and Hs 294T melanoma cells. Other synonyms for EDDR1 include CAK, CD167, and DDR.
