逆转录病毒基因组编码的Gag蛋白含有病毒组装所需的多种病毒原件,在核糖体合成后,Gag蛋白直接到达胞膜或内含体膜的结合位点进行组装并发育成非成熟的病毒体,然后被病毒蛋白水解酶裂解成基质(MA)、衣壳(CA)和核衣壳蛋白,从而组装成成熟的可感染的病毒颗粒。对于大多数逆转录病 The Gag protein encoded by the retrovirus genome contains many kinds of virus components required for virus assembly. After ribosome synthesis, the Gag protein directly reaches the binding sites of the membrane or the inclusion body membrane to assemble and develop into immature virions, It is then cleaved by the viral proteolytic enzymes into matrix (MA), capsid (CA) and nucleocapsid proteins, which assemble into mature, infective virions. For most retroviruses
