Webresidues (5). This protein acts as part of a co-receptor complex with the host cell CD4 protein. Association between CD4 and GP120 leads to conformational changes in these proteins that ultimately lead to membrane fusion between the host cell and the virus particle. The presence of this glycosylation acts as a natural barrier to defending immune WebThe function and physiological regulation of the oxytocin-receptor system is strongly steroid-dependent. This is, unexpectedly, only partially reflected by the promoter sequences in the oxytocin receptor and favors the idea that posttranscriptional mechanisms may also play a significant role for the physiological regulation of the oxytocin-receptor system.

The unique interaction between the oligosaccharide chains have different applications. First, it aids in quality control by identifying misfolded proteins. The oligosaccharide chains also change the solubility and polarity of the proteins that they are bonded to. For example, if the oligosaccharide chains are negatively charged, with enough density around the protein, they can repulse proteolytic enzymes away from the bonded protein. The diversity in interactions lends it… Web14 de abr. de 2013 · The surface of the HIV virion contains a glycoprotein called gp120 which allows it to attach to human immune system cells.
