Anti-SDK1 antibodies are used in the immunodetection of the protein sidekick cell adhesion molecule 1. In humans, the canonical protein has a reported length of 2213 amino acid residues and a mass of 242.1 kDa. Its subcellular localization is in the cell membrane. Up to 3 different isoforms have been reported for this protein. It is notably widely expressed in many tissue types. A member of the Sidekick protein family, SDK1 is reported to be an adhesion molecule that promotes lamina-specific synaptic connections in the retina. Post-translational modifications have been described, including glycosylation. Synonyms for this target antigen include protein sidekick-1 and sidekick homolog 1, cell adhesion molecule. SDK1 gene orthologs have been reported in the mouse, rat, bovine, zebrafish, chimpanzee and chicken species. Western Blot is a widely used application for the SDK1 antibodies listed below. In addition, Immunohistochemistry is also a common application.
