Physiopathological roles of vesicular nucleotide transporter (VNUT), an essential component for vesicular ATP release

Biochim Biophys Acta Biomembr. 2020 Dec 1;1862(12):183408. doi: 10.1016/j.bbamem.2020.183408. Epub 2020 Jul 9.

Abstract

Vesicular nucleotide transporter (VNUT) is the last identified member of the SLC17 organic anion transporter family, which plays a central role in vesicular storage in ATP-secreting cells. The discovery of VNUT demonstrated that, despite having been neglected for a long time, vesicular ATP release represents a major pathway for purinergic chemical transmission, which had been mainly attributed to ATP permeation channels. This article summarizes recent advances in our understanding of the mechanism of VNUT and its physiopathological roles as well as the development of inhibitors. Regulating the activity and/or the expression of VNUT represents a new and promising therapeutic strategy for the treatment of multiple diseases.
