{"product_id":"new-product-274441","title":"GRF-1 (phospho-Y1087) polyclonal antibody","description":"\u003cp\u003eGRF-1 (glucocorticoid receptor DNA-binding factor 1), also known as p190RhoGAP or simply p190, is a transcriptional regulator which binds to the promoter region of the glucocorticoid receptor gene and represses its expression. By repressing GR expression, GRF-1 acts to down-regulate Rho signaling, thereby mediating both actin cytoskeletal rearrangements and cell cycle events. Through its GAP domain, GRF-1 is thought to affect cytokinesis by regulating Rho activity; a regulation that is controlled by the ubiquination of the GTP binding region and subsequent degradation of GRF-1. Additionally, GRF-1 plays an important role in oligodendrocyte differentiation, a process that is absent in malignant glioma tumors, implicating GRF-1 as a possible tumor suppressor. GRF-1 expression is regulated by glucocorticoids and the expressed protein exists as two isoforms produced by alternative splicing events.\u003c\/p\u003e","brand":"ABCbiolab","offers":[{"title":"100ul \/ Rabbit \/ Human","offer_id":45804153110808,"sku":"ABCBW02531","price":348.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0590\/5652\/1400\/products\/758-7580448_monoclonal-antibody-png-transparent-png_98d01087-5a0e-4850-9026-dd8c9ccd6c94.png?v=1689737703","url":"https:\/\/danabiosci.com\/products\/new-product-274441","provider":"Dana Bioscience","version":"1.0","type":"link"}
