The role of envelope glycoprotein processing in murine leukemia virus infection.
The murine leukemia virus envelope protein is synthesized as a precursor molecule, Pr85env, which is proteolytically cleaved at an arginine residue to produce two mature envelope proteins, gp70 and p15(E). The results presented here indicate that mutation to lysine of the arginine found at the envelope precursor cleavage site results in a precursor which is cleaved with an efficiency at least 1...
متن کاملStructure of the murine leukemia virus envelope glycoprotein precursor.
The glycosylated env gene precurosr (Pr80env) of Moloney murine leukemia virus has been isolated by selective immunoprecipitation. Use of the drug tunicamycin to inhibit nascent glycosylation or specific cleavage with endoglycosidase H demonstrated that the precursor contained an apoprotein with a molecular weight of 60,000. The finished virion glycoprotein (gp70) was largely resistant to the a...
متن کاملCell fusion induced by the murine leukemia virus envelope glycoprotein.
To determine whether ecotropic murine leukemia virus (MuLV) envelope glycoproteins are sufficient to cause cell-to-cell fusion when expressed in the absence of virus production, we used an ecotropic MuLV, AKV, to construct env expression vectors that lack the gag and pol genes. The rat cell line XC, which undergoes cell-to-cell fusion upon infection with ecotropic MuLV, was transfected with wil...

از محوری ترین اثراتی که یک فیلم سینمایی ایجاد می کند دیالوگ هایی است که هنرپیش گان فیلم میگویند. به زعم یک فیلم ساز, یک شیوه متأثر نمودن مخاطب از اثر منظوره نیروی گفتارهای گوینده, مثل نیروی عاطفی, ترس آور, غم انگیز, هیجان انگیز و غیره, است. این مطالعه به بررسی این مسأله مبادرت کرده است که آیا نیروی فراگفتاری هنرپیش گان به مثابه ی اعمال گفتاری در پنج فیلم هالیوودی در نسخه های دوبله شده باز تولید...
15 صفحه اولRelation of GIX antigen of thymocytes to envelope glycoprotein of murine leukemia virus
Expression of Gix surface antigen on thymocytes is an inherited mendelian train of certain strains of mice. We report here the following new findings: (a) Gix antigen was found free in the serum of Gix+ mouse strains. (b) Expression vs. nonexpression of Gix antigen was invariably correlated with presence or absence of the group-specific antigen of Murine leukemia virus (MuLV) gp69/71 in the ser...
