pWITCH: a versatile two-hybrid assay vector for the production of epitope/activation domain-tagged proteins both in vitro and in yeast.


We describe the construction of a new vector, pWITCH, designed to facilitate the characterisation of proteins encoded by novel cDNAs isolated using either a one- or two-hybrid assay. Expression of directionally cloned cDNAs is directed in vivo in Saccharomyces cerevisiae from the inducible GAL10 promoter and in vitro from the T7 promoter, while translation… (More)
