| description | ARC3 acts as a Z-ring accessory protein involved in division site placement in chloroplast. ARC3 contains an N-terminal domain with similarities to FtsZ proteins and a C-terminal domain containing MORN (membrane occupation and recognition) motifs, linked by a novel middle domain, and was reported as a cytosolic chloroplast division component [, ]. ARC3 is distributed throughout the stroma and is also localized to a midplastid ring-like structure where it is recruited to the middle of the plastid by PARC6, which facilitates Z-ring remodeling during chloroplast division by promoting Z-ring dynamics. This reveals a novel function for MORN domains in regulating protein-protein interactions []. |
