Figure 3

Efficiency of Mistic homologues in promoting expression of C-terminally fused membrane proteins. Shown are three SDS-polyacrylamide gels stained with Coomassie Blue showing the successful expression of: (a) Alk3 (a TGF-β receptor); (b) CRFR2β (a GPCR); and (c) CCR5 (a GPCR), by fusion to the C-terminus of variations of Mistic from B. subtilis, B. licheniformis, B. mojavensis, and B. atrophaeus. Successful cleavage the fusion protein (upper arrows) at the protease sensitive linker between a particular cargo protein and its respective Mistic domain in the presence of thrombin (columns marked "+"), confirms the identity of the desired product (lower arrows).
