1. A non-natural cell, comprising:
- (a) a first nucleic acid molecule encoding a first fusion protein comprising a first multimerization domain, a first hydrophobic domain, and an actuator domain, wherein the first multimerization domain localizes extracellularly when the first fusion protein is expressed; and
(b) a second nucleic acid molecule encoding a second fusion protein comprising a binding domain and a second multimerization domain, and a second hydrophobic domain;
wherein a first bridging factor promotes the formation of a polypeptide complex on the non-natural cell surface with the bridging factor associated with and disposed between the multimerization domains of the first and second fusion proteins.

-
(a) a first fusion protein comprising a first multimerization domain, a first hydrophobic domain, and an actuator domain; (b) a second fusion protein comprising an extracellular binding domain, a second multimerization domain, and a second hydrophobic domain; and (c) a bridging factor; wherein the first fusion protein, second fusion protein, and bridging factor associate to form a polypeptide heterocomplex with the bridging factor associated with and disposed between the multimerization domains of the first and second fusion proteins.
