Most notably, Rev M4 forms trimer complexes with target RNA significantly less well than wild-type Rev, which is indicative of a multimerization defect. Rev M4 binds the high affinity site less well than wild-type Rev and the binding of subsequent molecules is similarly impaired. S54G;S56G mutant, which contains a double substitution at positions 54 and 56 as opposed to the double deletion in M7gave first and second dissociation constants very similar to those for M4 when assayed with our in vitro system Fig. Meikle, a wild relative of pigeonpea. The mutations have been shown to map to an exposed hydrophobic surface patch on the Rev protein 43and it was proposed that the mutant phenotype arises from localized structural changes in this surface region which disrupt the multimerization interfaces. Between residues 75 and 84 in the C-terminal portion of Rev lies a leucine-rich sequence termed the activation domain 34—36 ; this sequence is a nuclear export signal which is able to bind the conserved nuclear export factor Crm1 37— With these improved conditions we have been able to anonymous chat site for horny people up to 13 clearly defined bands on gels, corresponding to the RRE with from 1 to 13 Rev monomers bound.

The Rev protein of human immunodeficiency virus type 1 HIV-1 is essential for the late phase of infection of a cell, leading to the production of infectious virions 12 ; it acts post-transcriptionally to permit cytoplasmic expression of incompletely spliced HIV-1 mRNAs reviewed in 3. Furthermore, we have established that M7 is significantly defective in RNA binding, the essential initial event in the generation of a Rev response.

Rev M4 is confirmed by these results to be substantially deficient, whereas Rev M7 appears to be defective in RNA binding at the high affinity site, rather than specifically defective in multimerization. To avoid this, Rev-GST fusion proteins 54 have often been used for in vitro multimerization assays [e. Please check for further notifications by email.
