Abstract
Synthetic protein-binding tools based on anti-green fluorescent protein (GFP) nanobodies have recently emerged as useful resources to study developmental biology. By fusing GFP-targeting nanobodies to well-characterized protein domains residing in discrete sub-cellular locations, it is possible to directly and acutely manipulate the localization of GFP-tagged proteins-of-interest in a predictable manner. Here, we describe a detailed protocol for the application of nanobody-based GFP-binding tools, namely Morphotrap and GrabFP, to study the localization and function of extracellular and intracellular proteins in the Drosophila wing imaginal disc. Given the generality of these methods, they are easily applicable for use in other tissues and model organisms.
