STRUCTURAL BIOLOGY Building the Postsynaptic Density

The postsynaptic density (PSD) is a large and dynamic protein complex on the postsynaptic side of neural synapses that helps to communicate incoming signals to cytoplasmic targets. Shank proteins are located deep in the PSD and may be involved in organizing the structure of the complex. Baron et al. have determined the structure of the sterile alpha motif domain of a Shank protein and show that it forms large sheets composed of helical fibers stacked side by side. Sheets of the Shank protein may form a platform for the construction of the PSD complex.
