Impact of the Rev mRNA stability on the kinetics of the viral components synthesis in an activated cell. The curves are distinguished by the parameters values: curve 1 - k = 0.0009 min-1, curve 2 - k = 0.0014 min-1, curve 3 - k = 0.0015 min-1, curve 4 - k = 0.0016 min-1, k = ,. Simulations for the version of the model in which the Rev-dependent transport of 9 kb RNA and 4 kb RNA from the nucleus to the cytoplasm leads to the release of the RNA bound Rev proteins into the free cytoplasmic fraction. However, the interaction of Rev with 9 kb- and 4 kb RNAs in the cytoplasm does not take place. The simulations were performed with the model parameter values listed in Table 1.
