摘要： Four glycoproteins of apparent molecular weights 300,000, 140,000, 125,000, and 36,000 (gp300, gp140, gp125, and gp36) are detectable in human immunodeficiency virus type 2 (HIV-2) infected cells. The gp125 and gp36 are the external and transmembrane components, respectively, of the envelope glycoproteins of HIV-2 mature virions. The gp300, which is a dimeric form of gp140, the precursor of HIV-2 envelope glycoprotein, is probably formed by a pH dependent fusion in the endoplasmic reticulum. Such a doublet is also observed in cells infected with simian immunodeficiency virus (SIV), a virus closely related to HIV-2. On the other hand, the envelope glycoprotein precursor of HIV-1 does not form a dimer during its processing. Experiments carried out with various inhibitors of oligosaccharide trimming enzymes suggest that transient dimerization of the glycoprotein precursor is required for its efficient transport to the Golgi apparatus and for its processing. The gp300 is useful for detecting antibodies to HIV-2 antigens in human body fluids and for raising antibodies to gp300.

摘要： Characterization of the envelope transmembrane protein of human immunodeficiency virus type 2 (HIV-2) was carried out using murine polyclonal and monoclonal antibodies or patient sera specific for HIV-2 proteins. A 80-Mr glycoprotein (gp80) was produced in HIV-2 infected cells along with three other glycoproteins that were recently reported: the extracellular glycoprotein (gp125), the envelope glycoprotein precursor (gp140), and the transient dimeric form of gp140 (gp300). The gp125 and gp80 were detectable after the synthesis of gp140 and the formation of gp300. Among these four glycoproteins, only gp80 and gp125 were associated with HIV-2 virions. As the other glycoproteins, gp8O was recognized by all HIV-2 positive sera. A murine polyclonal antibody raised against the purified gp300 recognized all four glycoproteins. On the other hand, a monoclonal antibody raised against a synthetic polypeptide deduced from the sequence of the transmembrane glycoprotein of HIV-2, recognized gp140, gp300 and gp80; thus indicating that gp80 should be related to the transmembrane protein of the envelope. Dimerization of envelope glycoprotein precursor and the transmembrane glycoprotein was also observed in cells infected with simian immunodeficiency virus (SIV), a virus closely related to HIV-2. Dimerization of the envelope precursors might be essential for the processing of these glycooroteins into the mature products, extracellular and transmembrane glycoproteins. Furthermore, the dimeric form of the transmembrane glycoproteins might be important for the optimal structure of the virus and thus for its infectivity.

摘要： Character of the envelope transmembrane protein of human immunodeficiency virus type 2 (HIV-2) was carried out using murine polyclonal and monoclonal antibodies or patient sera specific for HIV-2 proteins. A 80-Mr glycoprotein (gp80) was produced in HIV-2 infected cells along with three other glycoproteins that were recently reported: the extracellular glycoprotein (gp125), the envelope glycoprotein precursor (gp140), and the transient dimeric form of gp140 (gp300). The gp125 and gp80 were detectable after the synthesis of gp140 and the formation of gp300. Among these four glycoproteins, only gp80 and gp125 were associated with HIV-2 virions. As the other glycoproteins, gp80 was recognized by all HIV-2 positive sera. A murine polyclonal antibody raised against the purified gp300 recognized all four glycoproteins. On the other hand, a monoclonal antibody raised against a synthetic polypeptide deduced from the sequence of the transmembrane glycoprotein of HIV-2, recognized gp140, gp300 and gp80; thus indicating that gp80 should be related to the transmembrane protein of the envelope. Dimerization of envelope glycoprotein precursor and the transmebrane glycoprotein was also observed in cells infected with simian immunodeficiency virus (SIV), a virus closely related to HIV-2. Dimerization of the envelope precursors might be essential for the processing of these glycoproteins into the mature products, extracellular and transmembrane glycoproteins. Furthermore, the dimeric form of the transmembrane glycoproteins might be important for the optimal structure of the virus and thus for its infectivity.
摘要翻译：使用鼠多克隆和单克隆抗体或特异于HIV-2蛋白的患者血清进行人类免疫缺陷病毒2型（HIV-2）的包膜跨膜蛋白的特征。在HIV-2感染的细胞中产生80-Mr糖蛋白（gp80）以及最近报道的三种其他糖蛋白：细胞外糖蛋白（gp125），包膜糖蛋白前体（gp140）和gp140（gp140）的瞬时二聚体形式）。在gp140的合成和gp300的形成之后，gp125和gp80是可检测的。在这四种糖蛋白中，只有gp80和gp125与HIV-2病毒粒子相关。作为其他糖蛋白，gp80被所有HIV-2阳性血清识别。针对纯化的gp300产生的鼠多克隆抗体识别所有四种糖蛋白。另一方面，从HIV-2的跨膜糖蛋白序列推断出的合成多肽产生的单克隆抗体，识别为gp140，gp300和gp80; 从而表明gp80应与信封的跨膜蛋白相关。在与HIV-2密切相关的猿猴免疫缺陷病毒（SIV）感染的细胞中也观察到包膜糖蛋白前体和跨膜糖蛋白的二聚体。包膜前体的二聚化对于将这些糖蛋白加工成成熟产物，细胞外和跨膜糖蛋白可能是必需的。此外，跨膜糖蛋白的二聚形式对于病毒的最佳结构以及因此其感染性可能是重要的。
