An electrostatic switching mechanism to control the lipid transfer activity of Osh6p
Osh6p and Osh7p are yeast lipid transfer proteins (LTPs) that must transiently interact with membranes but how they escape from the electrostatic attraction of the plasma membrane is unclear. Here authors show that Osh6p reduces its avidity for anionic membranes once it captures PS or PI4P, due to a...

| Sumario: | Osh6p and Osh7p are yeast lipid transfer proteins (LTPs) that must transiently interact with membranes but how they escape from the electrostatic attraction of the plasma membrane is unclear. Here authors show that Osh6p reduces its avidity for anionic membranes once it captures PS or PI4P, due to a molecular lid closing its lipid-binding pocket. |
