PDZ affinity chromatography: a general method for affinity purification of proteins based on PDZ domains and their ligands.
PDZ (PSD-95, DiscsLarge, ZO1) domains function in nature as protein binding domains within scaffold and membrane-associated proteins. They comprise ∼90 residues and make specific, high affinity interactions with complementary C-terminal peptide sequences, with other PDZ domains, and with phospholipids. We hypothesized that the specific, strong interactions of PDZ domains with their ligands woul...
متن کاملPDZ Proteins Bind, Cluster, and Synaptically Colocalize with Eph Receptors and Their Ephrin Ligands
Localizing cell surface receptors to specific subcellular positions can be critical for their proper functioning, as most notably demonstrated at neuronal synapses. PDZ proteins apparently play critical roles in such protein localizations. Receptor tyrosine kinases have not been previously shown to interact with PDZ proteins in vertebrates. We report that Eph receptors and their membrane-linked...
متن کاملA molecular-properties-based approach to understanding PDZ domain proteins and PDZ ligands.
PDZ domain-containing proteins and their interaction partners are mutated in numerous human diseases and function in complexes regulating epithelial polarity, ion channels, cochlear hair cell development, vesicular sorting, and neuronal synaptic communication. Among several properties of a collection of documented PDZ domain-ligand interactions, we discovered embedded in a large-scale expressio...
متن کاملPDZ domains: the building blocks regulating tumorigenesis.
Over 250 PDZ (PSD95/Dlg/ZO-1) domain-containing proteins have been described in the human proteome. As many of these possess multiple PDZ domains, the potential combinations of associations with proteins that possess PBMs (PDZ-binding motifs) are vast. However, PDZ domain recognition is a highly specific process, and much less promiscuous than originally thought. Furthermore, a large number of ...
متن کاملPDZ domains: More than just a glue.
P domains are part of a molecular scaffold that holds multiprotein signaling complexes together. It is generally believed that the role of PDZ domains is to position target ion channels, receptors, or other signaling molecules in correct spatial arrangement in relation to each other and to specialized regions of the cell (1–4). Two recent reports, one published in Cell (5) and another in this i...
