{"product_id":"ppp2r4-antibody-protein-phosphatase-2a-bha17102507","title":"PPP2R4 Antibody \/ Protein Phosphatase 2A","description":"\u003cp\u003ePPIases accelerate the folding of proteins. It catalyzes the cis-trans isomerization of proline imidic peptide bonds in oligopeptides. Acts as a regulatory subunit for serine\/threonine- protein phosphatase 2A (PP2A) modulating its activity or substrate specificity, probably by inducing a conformational change in the catalytic subunit, a proposed direct target of the PPIase. Can reactivate inactive phosphatase PP2A-phosphatase methylesterase complexes (PP2A(i)) in presence of ATP and Mg(2+) (By similarity). Reversibly stimulates the variable phosphotyrosyl phosphatase activity of PP2A core heterodimer PP2A(D) in presence of ATP and Mg(2+) (in vitro). The phosphotyrosyl phosphatase activity is dependent of an ATPase activity of the PP2A(D):PPP2R4 complex. Is involved in apoptosis; the function appears to be independent from PP2A.\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eFormat:\u003c\/strong\u003e Antigen affinity purified\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NSJ Bioreagents","offers":[{"title":"In 1X PBS, pH 7.4, with 0.09% sodium azide \/ 0.05 ml","offer_id":53042934088045,"sku":"F53899-0.05ML","price":205.0,"currency_code":"USD","in_stock":true},{"title":"In 1X PBS, pH 7.4, with 0.09% sodium azide \/ 0.2 ml","offer_id":53043013517677,"sku":"F53899-0.2ML","price":439.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7424\/7277\/files\/get_image_179d6067-d743-4e42-9eed-86e5fc9b7bdf.jpg?v=1771924026","url":"https:\/\/www.ebiohippo.com\/products\/ppp2r4-antibody-protein-phosphatase-2a-bha17102507","provider":"BioHippo","version":"1.0","type":"link"}
