The HIV-1 regulatory proteins tat and rev are both RNA binding proteins which recognize sequences in duplex RNA which are close to structural distortions. Here we identify phosphate contacts which are critical for each binding reaction by use of a new method. Model RNA binding sites are constructed carrying substitutions of individual phosphodiesters by(More)
We have reported previously that the three heat shock proteins hsp56, hsp70, and hsp90 exist together in a heterocomplex in human lymphocyte cytosol (Sanchez, E. R., Faber, L. E., Henzel, W. J., and Pratt, W. B. (1990) Biochemistry 29, 5145-5152). All three of these proteins also exist in the native glucocorticoid receptor heterocomplex isolated from WCL2(More)
