Constitutive activation of the Ras pathway triggers an irreversible proliferation arrest reminiscent of replicative senescence. Transcription of this gene is upregulated in response to activation of the Ras pathway, but not under other conditions that induce senescence. RIS1 is similar to a rat cell surface receptor proposed to function in a neuronal survival pathway. RIS1 is not upregulated in association to any of the above-mentioned processes, but exclusively during Ras-senescence. Furthermore, RIS1 is also upregulated by the transcriptional factor Ets2, which is a known mediator of Ras-induced senescence. Interestingly, RIS1 is located at chromosomal position 3p21.3 and, more specifically, it is included in a short segment of just 1 Mb previously defined by other investigators for its tumor-suppressor activity.
Mouse Transmembrane protein 158 (TMEM158) ELISA Kit employs a two-site sandwich ELISA to quantitate TMEM158 in samples. An antibody specific for TMEM158 has been pre-coated onto a microplate. Standards and samples are pipetted into the wells and anyTMEM158 present is bound by the immobilized antibody. After removing any unbound substances, a biotin-conjugated antibody specific for TMEM158 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 TMEM158 bound in the initial step. The color development is stopped and the intensity of the color is measured.
