Ivy1 is a negative regulator of Gtr-dependent TORC1 activation [PDF]

Journal of Cell Science, 2018
ABSTRACT The highly conserved TORC1 complex controls cell growth in response to nutrients, especially amino acids. The EGO complex activates TORC1 in response to glutamine and leucine. Here, we demonstrate that the I-BAR domain-containing protein Ivy1 colocalizes with Gtr1 and Gtr2, a heterodimer of small GTPases that are part of the EGO

Free-stream turbine start-up under load [PDF]

E3S Web of Conferences, 2019
Free-stream turbine is an alternative to classical high-head turbines. On one hand, it produces less power, on the other hand, it requires less ser-vice and construction and might be an eco-friendlier option.
