Nanobody-Directed Specific Degradation of Proteins by the 26S-Proteasome in Plants

Front Plant Sci. 2018 Feb 9:9:130. doi: 10.3389/fpls.2018.00130. eCollection 2018.

Abstract

Here, we present data showing the directed degradation of target proteins recognized by a specific nanobody in transgenic plants. Green fluorescent protein was depleted by a chimeric nanobody fused to a distinct F-box domain, which enables protein degradation via the ubiquitin proteasome pathway. This technique could thus be used to knock out other proteins of interest in planta using specific, high-affinity binding proteins.
