Here, the authors perform a large-scale, high-throughput biochemical assay to determine the compatibility of over 300,000 domain recombination variants of the inward rectifier K+ channel Kir2.1. They derive rules for designing domain insertion variants that fold and traffic to the cell surface and conclude that the insertion of domains at protein termini is evolutionary favoured.
