Allosteric Modulation
Allosteric modulation has long been recognized as a general and widespread mechanism for the control of protein function. Modulators bind to regulatory sites distinct from the active site on the protein, resulting in conformational changes that may profoundly influence protein function. This concept…

Polar auxin transport: translating environmental signals into plant developmental responses
1. What is the exact role of PIN proteins in PAT? 2. How is PIN polarity established, and how is it modulated by AGC kinase-mediated phosphorylation? 3. What is the role of the AGC kinase, as modulators of PAT, in translating environmental signals, such as gravity, light or mechanical stress, to plant…

Regulation of the arabidopsis AGC kinase PINOID by PDK1 and the microtubule cytoskeleton
Plants, are sessile organisms, have developed strategies to adapt to changes in their environment, in part by altering their growth and development.

Calcium-dependent regulation of auxin transport in plant development
The plant hormone auxin regulates plant growth and development through polar cell-to-cell transport-generated maxima and minima. PIN FORMED (PIN) auxin efflux carriers determine the direction of this auxin flow through their asymmetric placement on the plasma membrane (PM).
