Anti-ALPK1 antibodies are used in the immunodetection of the protein alpha kinase 1. In humans, the canonical protein has a reported length of 1244 amino acid residues and a mass of 138.9 kDa. Its subcellular localization is in the cytoplasm. Up to 2 different isoforms have been reported for this protein. It is reported to be highly expressed in the liver. A member of the Alpha-type protein kinase protein family, ALPK1 is a type of serine/threonine-protein kinase that detects bacterial pathogen-associated molecular pattern metabolites (PAMPs) and initiates an innate immune response, a critical step for pathogen elimination and engagement of adaptive immunity. Synonyms for this target antigen include chromosome 4 kinase, lymphocyte alpha-kinase, lymphocyte alpha-protein kinase, and alpha-protein kinase 1. ALPK1 gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species. Some ALPK1 antibodies may have been used in research and have associated citations. Western Blot is a widely used application for these antibodies. ELISA and Immunohistochemistry are also common applications.
