CRY-BARs: Versatile light-gated molecular tools for the remodeling of membrane architectures.

ABSTRACT: BAR (Bin, Amphiphysin, and Rvs) protein domains are responsible for the generation of membrane curvature and represent a critical mechanical component of cellular functions. Thus, BAR domains have great potential as components of membrane-remodeling tools for cell biologists. In this work, we describe the design and implementation of a family of versatile light-gated I-BAR (inverse BAR) domain containing tools derived from the fusion of the Arabidopsis thaliana cryptochrome 2 photoreceptor and I-BAR protein domains ("CRY-BARs") with applications in the remodeling of membrane architectures and the control of cellular dynamics. By taking advantage of the intrinsic membrane-binding propensity of the I-BAR domain, CRY-BARs can be used for spatial and temporal control of cellular processes that
