Anti-WNK1 antibodies are used in the immunodetection of the protein WNK lysine deficient protein kinase 1. In humans, the canonical protein has a reported length of 2382 amino acid residues and a mass of 250.8 kDa. Its subcellular localization is in the cytoplasm. Up to 6 different isoforms have been reported for this protein. It is found to be widely expressed, with highest levels observed in the testis, heart, kidney and skeletal muscle. A member of the Ser/Thr protein kinase protein family, WNK1 is known to be a serine/threonine kinase that plays an important role in the regulation of electrolyte homeostasis, cell signaling, survival, and proliferation. Synonyms for this target antigen include erythrocyte 65 kDa protein, prostate-derived sterile 20-like kinase, protein kinase with no lysine 1, protein phosphatase 1, regulatory subunit 167, and serine/threonine-protein kinase WNK1. A number of WNK1 antibodies have been mentioned in research publications and have associated citations. Western Blot is a widely used application for these antibodies. ELISA and Immunohistochemistry are also common applications.
