    Premature processing of mouse mammary tumar virus Gag polyprotein impairs intracellular capsid assembly

  • Original language description

    We described an unusual intracellular processing of the mouse mammary tumor virus (MMTV) Gag polyprotein in human cells transiently expressing MMTV. The same specific cleavage products of the viral protease were seen for the wild type as well as for nonmyristylated mutant of MMTV Gag polyprotein defective in the particle release. Inactivation of the viral protease resulted in more stable Gag polyprotein and in accumulation of intracytoplasmic particles for nonmyristylated Gag. Our data indicates that protease activation in betaretrovirus can occur independently of budding.

    Předčasné štěpení Gag polyproteinu viru myšího tumoru prsní žlázy MMTV negativně ovlivňuje intracelulární tvorbu virionu

  • Czech description

    U myšího viru MMTV bylo prokázáno specifické štěpení strukturního polyproteinu Gag virovou proteasou uvnitř buňky nezávisle na procesu pučení. Inaktivací virové proteasy bylo dosaženo zvýšení účinnosti tvorby intracelulárních virových částic u Gag polyproteinu divokého typu i jeho transportního mutantu. Jedná se o unikátní vlastnost viru MMTV, která u ostatních betaretrovirů pozorována nebyla.
