Abstract in another language

Signaling proteins comprise interaction and effector modules connected by linkers. Throughout evolution, these recurring modules have multiply been recombined to produce the present-day plethora of signaling proteins. Likewise, modular recombination lends itself to the engineering of hybrid signal receptors, whose functionality hinges on linker topology, sequence, and length. Often, numerous linkers must be assessed to obtain functional receptors. To expedite linker optimization, we devised the PATCHY strategy (primer-aided truncation for the creation of hybrid proteins) for the facile construction of hybrid gene libraries with defined linker distributions. Empowered by PATCHY, we engineered photoreceptors whose signal response was governed by linker length: whereas blue-light-repressed variants possessed linkers of 7n or 7n+5 residues, variants with 7n+1 residues were blue-light-activated. Related natural receptors predominantly displayed linker lengths of 7n and 7n+5 residues but rarely of 7n+1 residues. PATCHY efficiently explores linker sequence space to yield functional hybrid proteins including variants transcending the natural repertoire of signaling proteins.
