– Mitophagy visualization fluorescent sensor, mito-SRAI
Mitophagy is a selective autophagy degrading stress-damaged mitochondria.
Dr. Miyawaki Atsushi and Dr. Katayama Hiroyuki of RIKEN Center for Brain Science (CBS) and Dr. Hioki Hiroyuki of Juntendo University and their colleagues have developed mito-SRAI, a fluorescent sensor that can quantitatively visualize mitophagy both in live and fixed conditions.
The mito-SRAI is composed of TOLLES (cyan) fluorescent protein that is resistant to acidic condition and protein degradation in lysosomes, and YPet (yellow) fluorescent protein whose fluorescence intensity changes according to pH. The mito-SRAI is specifically localized in mitochondria and the mitophagy can be observed by representative ratio (TOLLES/YPet) images by expressing in cultured cells. The mito-SRAI has been genetically engineered to confer tolerance of fluorescence in fixed conditions.
The mito-SRAI might support drug discovery assays testing a huge amount of fixed biological samples and experimental animal studies (Katayama, H. et al., Cell, 181 (5): 1176-1187, 2020. PMID: 32437660).
