Anti-PDSS2 antibodies are used in the immunodetection of the protein decaprenyl diphosphate synthase subunit 2. In humans, the canonical protein has a reported length of 399 amino acid residues and a mass of 44.1 kDa. Its subcellular localization is in the mitochondria. Up to 2 different isoforms have been reported for this protein. It is notably widely expressed in many tissue types. A member of the FPP/GGPP synthase protein family, PDSS2 is reported to be a heterotetrameric enzyme that catalyzes the condensation of farnesyl diphosphate (FPP), which acts as a primer, and isopentenyl diphosphate (IPP) to produce prenyl diphosphates of varying chain lengths and participates in the determination of the side chain of ubiquinone. Synonyms for this target antigen include all-trans-decaprenyl-diphosphate synthase subunit 2, decaprenyl pyrophosphate synthase subunit 2, decaprenyl pyrophosphate synthetase subunit 2, and all trans-polyprenyl-diphosphate synthase PDSS2. A number of PDSS2 antibodies have been mentioned in research publications and have associated citations. Western Blot is a widely used application for these antibodies. In addition, Immunohistochemistry is also a common application.
