Similarly, sensing of glutamine-induced hepatocyte swelling by integrins feeds into ... hepatocyte swelling [12,13], insu- lin-induced hepatocyte swelling is registrated by the integrin system, leading to a Src-dependent activation of the p38-type MAPK and thereby inhibit...

The C-terminal helices show a clear handedness, and two of the rings face in the opposite direction in the membrane ... to the other two, forming the same pattern as in the AFM surface representation of Fig. 2A.

... c subunit, giving rise to a  16 kDa protein with two hairpins [20]. Most important, the ion-binding site is not conserved in hairpin 1. If one assumes the same number of hairpins in V 0 and F 0 , the ... rotor of V 1 V 0 - ATPases has only half the number of ion-binding sites. This is seen as the reason for the apparent inab- ility of V 1 V 0 -ATPases to catalyze ATP...
