Anti-PALS1 antibodies are used in the immunodetection of the protein protein associated with LIN7 1, MAGUK p55 family member. In humans, the canonical protein has a reported length of 675 amino acid residues and a mass of 77.3 kDa. Its subcellular localization is in the Golgi and cell membrane. Up to 2 different isoforms have been reported for this protein. It is noted to be expressed at the outer limiting membrane in the retina. A member of the MAGUK protein family, PALS1 is reported to play a role in tight junction biogenesis and in the establishment of cell polarity in epithelial cells. Synonyms for this target antigen include MAGUK p55 subfamily member 5, membrane palmitoylated protein 5, membrane protein, palmitoylated 5 (MAGUK p55 subfamily member 5), protein associated with LIN7 1, MAGUK family member, and protein PALS1. PALS1 gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species. A number of PALS1 antibodies have been mentioned in research publications and have associated citations. These antibodies are most commonly used in Western Blot experiments, among other applications.
