The poly(ADP-ribose) polymerase (PARP) tankyrase-1 contains an ankyrin-repeat domain that binds to various partners, including the telomeric protein TRF1 (telomere-repeat-binding factor 1) and the vesicular protein IRAP (insulin-responsive aminopeptidase). TRF1 binding recruits tankyrase-1 to telomeres and allows its PARP activity to regulate telomere homoeostasis. By contrast, IRAP binding and the Golgi co-localization of tankyrase-1 with IRAP might allow tankyrase-1 to affect the targeting ofIRAP-containing vesicles. A closely related protein, tankyrase-2, has also been implicated in vesicular targeting. Unlike tankyrase-1, tankyrase-2 has not been shown to have PARP activity. In addition, it has not been implicated in telomere homoeostasis, because it did not interact with TRF1 in previous studies.
Human Tankyrase-2 (TNKS2) ELISA Kit employs a two-site sandwich ELISA to quantitate TNKS2 in samples. An antibody specific for TNKS2 has been pre-coated onto a microplate. Standards and samples are pipetted into the wells and anyTNKS2 present is bound by the immobilized antibody. After removing any unbound substances, a biotin-conjugated antibody specific for TNKS2 is added to the wells. After washing, Streptavidin conjugated Horseradish Peroxidase (HRP) is added to the wells. Following a wash to remove any unbound avidin-enzyme reagent, a substrate solution is added to the wells and color develops in proportion to the amount of TNKS2 bound in the initial step. The color development is stopped and the intensity of the color is measured.
