The small GTPase Rac and the second messenger cGMP (guanosine 3′,5′-cyclic monophosphate) are critical regulators of diverse cell functions. When activated by extracellular signals via membrane signaling receptors, Rac executes its functions through engaging downstream effectors such as p21-activated kinase (PAK), a serine/threonine protein kinase. However, the molecular mechanism by which membrane...
In a two-wavelength phase-shifting speckle interferometer for object contouring one usually obtains only the height coordinate of the object surface which is parallel to the viewing direction (here denoted as z-coordinate). In order to measure the lateral surface coordinates x and y by the same technique the light source is shifted in two directions (denoted as u andv ) perpendicular to the optical...
