Fig. 1. The interaction of clone 6 and P56 in yeast. (A) Yeast strain Y190 was co-transfected with the following pairs of expression vectors and plated onto the selection medium without histidine: (1) BD–vector + AD–clone 6; (2) BD–P56 + AD–SV40 large T-antigen; (3) BD–P56 + AD–vector; (4) BD–P53 + AD–clone 6; (5) BD–P56 + AD–clone 6; and (6) BD–P53 + AD–SV40 large T-antigen. (B) Partial cDNA sequence of clone 6. (C) Maps of full-length Int-6/P48 and clone 6.
