Fig. 5. (A) Schematic representation of the different genomic fragments encoding the Y. lipolytica calnexin protein selected in the two-hybrid library screen using the Gal4BD-Sbh1p fusion protein as the bait. The position of the fusion point, relative to the initiator codon of YlCNX1, with the Gal4p activating domain is indicated. (B) Schematic representation of the different deletions of Cnx1p tested for their interaction with Sbh1p in the two-hybrid assay.
