NIHMS539904-supplement-supplement_1.pdf Rabbit polyclonal to AKR1D1 (2.1M) GUID:?464FEAA7-01DE-4961-AFE6-CF1FD08F5D37 Abstract Background Statins have antiinflammatory and antiatherogenic effects that have been attributed to inhibition of RHO protein geranylgeranylation in inflammatory cells. The activity of protein geranylgeranyltransferase type I (GGTase-I) is definitely widely believed to promote membrane association and activation of RHO family proteins. However, we recently showed that knockout of GGTase-I in macrophages activates RHO proteins and proinflammatory signaling pathways, leading to improved cytokine production and rheumatoid arthritis. In this study, we asked whether the improved inflammatory signaling of GGTase-ICdeficient macrophages would influence the development of atherosclerosis in low-density lipoprotein receptorCdeficient mice. Methods and Results Aortic lesions in mice lacking GGTase-I in macrophages (motif and undergo posttranslational modification having a 20-carbon geranylgeranyl lipid.1 The reaction is catalyzed by protein geranylgeranyltransferase type I (GGTase-I), a cytosolic enzyme composed of a unique subunit encoded by and an subunit that is shared with protein farnesyltransferase.1 The geranylgeranylation and farnesylation reactions, which are conserved from candida to humans, render the carboxyl terminus of proteins more hydrophobic and promote their interactions with membranes and additional proteins within cells. Probably the most well-studied protein substrates for GGTase-I are RHOA,.
