Enzyme SSH1 impairs disposal of accumulating cellular garbage, leading to brain cell death

(University of South Florida (USF Health)) The protein p62 plays a major role in clearing misfolded tau proteins and dysfunctional mitochondria, the energy powerhouse in all cells including neurons. Neuroscientists at the University of South Florida Health (USF Health) Byrd Alzheimer's Center report for the first time that the protein phosphatase Slingshot-1, or SSH1 for short, disrupts p62's ability to function as an efficient 'garbage collector' and thereby impairs the disposal of both damaged tau and mitochondria leaking toxins.
