cLIPS2
Taxonomy: Mechanism Branch / Architecture. Workflows sit above the mechanism and technique branches rather than replacing them.
Summary
cLIPS2 is a light-responsive multi-component switch identified from small libraries of cLIPS1 variants in a higher-throughput yeast screen. It binds human eIF4E in a light-dependent manner in vitro and inhibits translation in vivo in yeast harboring human eIF4E, with improved optical control relative to screened cLIPS1 variants.
Usefulness & Problems
Why this is useful
cLIPS2 is useful as an optogenetic regulator of eukaryotic translation initiation because it enables light-dependent engagement of human eIF4E and corresponding inhibition of translation in yeast. The reported improved degree of optical control suggests value for experiments requiring tighter light responsiveness than the screened cLIPS1 variants provided.

We identified cLIPS1 (circularly permuted LOV inhibitor of protein synthesis 1), a fusion of a segment of 4EBP2 and a circularly permuted version of the LOV2 domain from Avena sativa, as a photoactivated inhibitor of translation.

We show that these constructs can both inhibit translation in yeast harboring a human eIF4E in vivo
Problem solved
cLIPS2 helps address the problem of achieving externally controllable inhibition of translation initiation through human eIF4E. The source specifically positions it as a product of a yeast discovery system for optogenetic inhibitors of eukaryotic translation initiation and a higher-throughput screen for improved optical control.
Problem links
supports analysis of local translation with improved spatial and temporal resolution
LiteratureIt addresses the need to resolve local translation events in space and time rather than treating protein synthesis as a bulk process.

cLIPS2 was identified by adapting the yeast screen to higher throughput and testing small libraries of cLIPS1 variants. The available evidence indicates use in yeast harboring human eIF4E and dependence on light input, but it does not specify construct composition, cofactors, expression details, or delivery strategy.
The supplied evidence does not provide quantitative performance metrics, domain architecture, illumination wavelength, dynamic range, or kinetic parameters for cLIPS2. Validation is limited to in vitro binding and yeast-based in vivo translation inhibition, with no independent replication provided here.
