Background: Pleckstrin homology (PH) domains constitute a structurally conserved family present in many signaling and regulatory proteins. PH domains have been shown to bind to phospholipids, and many function in membrane targeting. They generally have a strong electrostatic polarization and interact with negatively charged phospholipids via the positive pole. On the basis of electrostatic modeling,...
Residual dipolar couplings are useful global structural restraints. The dipolar couplings define the orientation of a vector with respect to the alignment tensor. Although the size of the alignment tensor can be derived from the distribution of the experimental dipolar couplings, its orientation with respect to the coordinate system of the molecule is unknown at the beginning of structure determination...
Pleckstrin homology (PH) domains are found in many proteins involved in signal transduction or cytoskeletal organization. The general function for the domain is still unclear; phospholipid binding of some PH domains and a strong electrostatic polarization in the experimental structures suggest a role in localization on membranes. We have analyzed the electrostatic properties and the spatial amino...
