Method & Evidence

AimTo develop a versatile, single-component optogenetic toolkit for precise spatiotemporal control of microtubule organization and dynamics in living systems.

MethodGenetic engineering and optogenetic manipulation

ProcedureResearchers engineered single-component probes by replacing native multimerization motifs with a blue light-responsive oligomerization domain. These probes, including OptoMT, OptoTIP, OptoMotor, and OptoSAW, were designed to reversibly label microtubule polymers, track plus-ends, activate kinesin for cargo transport, and trigger microtubule disassembly. The toolkit was then used to investigate the impact of local microtubule integrity on lysosomal trafficking and ER-associated signaling.
