SponGee: A Genetic Tool for Subcellular and Cell-Specific cGMP Manipulation (Cell Reports)

Ros et al. developed SponGee, a genetically encoded cGMP chelator that enables the manipulation of this second messenger in single cells with subcellular specificity. SponGee alters the migration of developing cortical neurons in vivo. Lipid raft targeting of SponGee prevents axon repulsion, in contrast to exclusion from this subcellular compartment.
