We examined intercadherin interactions in epithelial A-431 cells producing endogenous E-cadherin and recombinant forms of E-cadherin tagged either by myc or by flag epitopes. Three distinct E-cadherin complexes were found. The first is a conventional E-cadherin-catenin complex consisting of one E-cadherin molecule linked either to beta-catenin/alpha-catenin or to plakoglobin/alpha-catenin dimer...
The bacterial multidrug transporter EmrE is a dual-topology membrane protein and as such is able to insert into the membrane in two opposite orientations. The functional form of EmrE is a homodimer; however, the relative orientation of the subunits in the dimer is under debate. Using EmrE variants with fixed, opposite orientations in the membrane, we now show that, although the proteins are abl...
Coiled coils consist of bundles of two or more alpha-helices that are aligned in a parallel or an antiparallel relative orientation. The designed peptides, Acid-p1 and Base-p1, associate in solution to form a parallel, heterodimeric two-stranded coiled coil [O'Shea, E. K., Lumb, K. J., and Kim, P. S. (1993) Curr. Biol. 3, 658]. The buried interface of this complex is formed by hydrophobic Leu r...
