The present invention relates to methods of identifying a molecule from a library of molecules that inhibits binding of human immunodeficiency virus nucleocapsid 7 polypeptide (NCp7) to an oligonucleotide which comprises admixing an NCp7 polypeptide with at one labeled HIV-1 psi-site oligonucleotide and an amount of the molecule to be tested under binding conditions; and determining the amount of oligonucleotide bound to the NCp7 polypeptide, wherein a decrease in the amount of oligonucleotide bound in the presence of the molecule compared with the amount of oligonucleotide bound in the absence of the molecule indicates that the molecule inhibits binding of NCp7 polypeptide to the oligonucleotide.
本发明涉及从抑制人类免疫缺陷病毒核壳7
多肽(NCp7)与寡核苷酸结合的分子库中鉴定分子的方法,该方法包括在结合条件下将NCp7
多肽与一个标记的HIV-1 psi-位点寡核苷酸和一定量的待测分子混合;确定与 NCp7
多肽结合的寡核苷酸量,其中,与没有该分子时结合的寡核苷酸量相比,有该分子时结合的寡核苷酸量减少,表明该分子抑制了 NCp7
多肽与寡核苷酸的结合。
