Protocol update to: Protocol for rapid manipulation of mitochondrial morphology in living cells using inducible counter mitochondrial morphology

Disruption of mitochondrial morphology occurs during various diseases, but the biological significance is not entirely clear. Here, we describe a detailed step-bystep protocol for a chemically inducible dimerization (CID) system-based synthetic protein device, termed inducible counter mitochondrial morphology (iCMM). This system allows artificial manipulation of mitochondrial morphology on a timescale of minutes in living mammalian cells. We also describe an AI-assisted image processing approach. For complete details on the use and execution of this protocol, please refer to Miyamoto et al.1 This protocol provides an updated version of the method described by Miyamoto et al.2
