New VCell Model from the Hille lab

June 9th, 2016|News, VCell Posts|

VCell models were used to quantitatively analyze FRET measurements were used to demonstrate that voltage-sensing phosphatases (VSPs) have catalytic activity for PIP3 (Keum et al. 2016.  Phosphoinositide 5- and 3-phosphatase activities of a voltage-sensing phosphatase in living cells show identical voltage dependence. Proc Natl Acad Sci U S A. 10.1073/pnas.1606472113, PMID 27222577).  Find the public VCell model here.
