ESCRT-0 regulates AMPA receptor currents and Ca2+- dependent signaling

Mahsa Pourhamzeh, Lara E. Dozier, Amanda Wilpitz, Yixing Du, Daniel B. McClatchy, Mariel Kristine B Micael, Joshua E. Mayfield, Stephen K. Gilmore-Hall, Josephina E Ronson, Katrin Soldau, Donald P. Pizzo, Brent D. Aulston, Erin E. Sullivan, Timothy F. Shay, Jin Wang, , Christina J. Sigurdson

This study shows that Hrs, an ESCRT-0 protein, modulates AMPA receptor currents and Ca2+-dependent signaling by sensing and responding to neuronal activity at synapses.
