Ras GTPases are lipid-anchored G proteins. which play a fundamental role in cell signaling processes. Electron micrographs of immunogold-labeled Ras have shown that membrane-bound Ras molecules segregate into nanocluster domains. Several models have been developed in attempts to obtain quantitative descriptions of nanocluster formation. https://countryscenesaddleryandpetsuppliers.shop/product-category/close-contact-conventional-harness/
