Engineering receptors in the secretory pathway for orthogonal signalling control

Artificial receptors targeted to the secretory pathway often fail to exhibit the expected activity due to post-translational modifications and/or improper folding. Here, the authors engineer diverse synthetic receptors that reside in the cytoplasm, inside the endoplasmic reticulum, or on the plasma membrane through orientation adjustment of the receptor parts and by elimination of dysfunctional PTMs sites.
