The participation of amyloids in neurodegenerative diseases and functional processes has triggered the quest for methods allowing their direct detection in vivo. Despite the plethora of data, those methods are still lacking. The autofluorescence from the extended β-sheets of amyloids is here used to track fibrillation of S. cerevisiae Golgi Reassembly and Stacking Protein (Grh1). Grh1 has been implicated in starvation-triggered unconventional protein secretion (UPS), and here its participation also in heat shock response (HSR) is suggested. Fluorescence Lifetime Imaging (FLIM) is used to detect fibril autofluorescence in cells (E. coli and yeast) under stress (starvation and higher temperature). The formation of Grh1 large complexes under stress is further supported by size exclusion chromatography and ultracentrifugation. The data show for the first time in vivo detection of amyloids without the use of extrinsic probes as well as bring new perspectives on the participation of Grh1 in UPS and HSR.
