A deletion mutant encoding the integrin beta3(4I-F56) with an additional Gln at the carboxyl terminus was found occassionally when we were constructing a counterselection yeast two-hybrid assay modle. This mutant exhibited strong transcriptional activation in yeast cells, bearing the Escherichia coli lacZ reporter gene encoding the beta-galactosidase under the transcriptional control of GAL4 promoter and TATA box. Further analysis revealed that the region between the amino acid residues 23C to S77, an acidic domain involved in the function of several transcriptional activators were critical for optimal level of transactivation.
