TABLE 3.

Transcriptional activation of lacZ by the interaction of NC protein and Ψ RNA

RNA hybrid^a	Fusion protein^a	Activation^b
HIVΨ-MS2	Gal4AD-HIV Gag	+++
HIVΨ-MS2	Gal4AD-HIV NC	+++
HaMSVΨ-MS2	Gal4AD-HIV NC	+++
IRE-MS2	Gal4AD-HIV NC	+++
—^c	Gal4AD-HIV NC	−

^a,b As in Table 1, except that the transformants were selected for uracil and leucine prototrophy for 4 days due to lower growth rate. Yeast colonies transformed only with pGal4AD-HIV NC were selected for leucine prototrophy.

—, no plasmid encoding an RNA hybrid was introduced.
