摘要: Seven-transmembrane segment, G protein-coupled receptors (GPCRs) play important roles in many biological processes which pharmaceutical intervention may be useful. High level expression and native purification of GPCRs are steps the biochemical structural characterization these molecules. Here, we describe enhanced mammalian cell a codon-optimized variant chemokine receptor CCR5, GPCR that plays central role entry human immunodeficiency virus-1 (HIV-1) into immune cells. CCR5 could solubilized its state as determined by ability to precipitated 2D7, conformation-dependent anti-CCR5 antibody, HIV-1 gp120 envelope glycoprotein. The 2D7 antibody recognized immature mature forms equally, whereas preferentially form, result underscores for posttranslational modification coreceptor function. methods described herein contribute analysis likely applicable other GPCRs.
