Outline of Final Research Achievements

We analyzed the functions of VCP, a major ATPase in the cell, in physiological and pathological conditions, and revealed the followings: Suppression of VCP ATPase activities could contribute to reduce the consumption of cellular ATP. VCP could form fiver-like structure, which reduced its ATPase activities. Our newly developed chemical compounds, named KUSs, could suppress VCP ATPase activities without suppressing cellular VCP functions, and KUS could suppress the onset and retard the progression of mouse models of retinitis pigmentosa and glaucoma.
