1965Jrnl. Amer. Chem. Soc. LXXXVII. 659/1 This strong trans-activation undoubtedly plays an important role in the catalytic activity and facile ligand-exchange reactions observed for platinum metal-tin chloride complexes. 1970Jrnl. Molecular Biol. XLIX. 402 It is assumed that the N product is also involved in trans-activation of this segment in the presence of immunity. 1973Molecular & Gen. Genetics CXXVII. 338 The efficiency of transactivation seems to vary considerably within different cells of one population. 1988Nature 13 Oct. 606/2 The LTR also includes the TAR sequence which is located within the R region and functions as the target for tat transactivation. |
