Anti-PASK antibodies are used in the immunodetection of the protein PAS domain containing serine/threonine kinase. In humans, the canonical protein has a reported length of 1323 amino acid residues and a mass of 142.9 kDa. Its subcellular localization is in the nucleus and cytoplasm. Up to 3 different isoforms have been reported for this protein. It is widely expressed across many tissue types. A member of the CAMK Ser/Thr protein kinase protein family, PASK is known to be a protein kinase involved in energy homeostasis and protein translation. Post-translational modifications have been described, including phosphorylation. Synonyms for this target antigen include STK37, PAS domain-containing serine/threonine-protein kinase, per-arnt-sim (PAS) domain kinase, and PASKIN. PASK gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species. A number of PASK antibodies have been mentioned in research publications and have associated citations. Western Blot is a widely used application for these antibodies. Immunofluorescence and Immunohistochemistry are also common applications.
