• PubMed Abstract: 
  

  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, however, we have previously identified a class of PH domains with a predominantly negative charge and predicted that these domains recognize other targets. Here, we report the first experimental structure of such a PH domain.
