HIV ENV PROTEINS WITH MODIFICATIONS IN THE V3 LOOP

摘要

The invention concerns modification of the V3 loop of the HIV envelope glycoprotein in order to alter its Tat-binding properties. The invention provides a mixture of (i) a HIV Tat polypeptide and (ii) a HIV Env polypeptide, wherein the Env polypeptide has one or more mutations in its V3 loop. Also a method comprising a step of: combining a HIV Env polypeptide with a HIV Tat polypeptide, wherein the Env polypeptide has one or more mutations in its V3 loop. Also a mixture of (i) a HIV Tat polypeptide and (ii) a polypeptide comprising a fragment of a V3 loop of a HIV Env polypeptide.
