Modulating organelle distribution using light-inducible heterodimerization in C. elegans.

ABSTRACT: The relative positioning of organelles underlies fundamental cellular processes, including signaling, polarization, and cellular growth. Here, we describe the usage of a light-dependent heterodimerization system, LOVpep-ePDZ, to alter organelle positioning locally and reversibly in order to study the functional consequences of organelle positioning. The protocol gives details on how to accomplish expression of fusion proteins encoding this system, describes the imaging parameters to achieve subcellular activation in C. elegans, and may be adapted for use in other model systems. For complete details on the use and execution of this protocol, please refer to De Henau et al. (2020).
