The PDZ domain is a common structural domain of 80-90 amino-acids found in the signaling proteins of bacteria, yeast, plants, and animals[1]. PDZ is an acronym combining the first letters of three proteins — post synaptic density protein (PSD95), Drosophila disc large tumor suppressor (DlgA), and zonula occludens-1 protein (zo-1) — which were first discovered to share the domain. PDZ domains are also referred to as DHR (Dlg homologous region) or GLGF (glycine-leucine-glycine-phenylalanine) domains. These domains help anchor transmembrane proteins to the cytoskeleton and hold together signaling complexes[2].
There are roughly 260 human PDZ domains, though since several PDZ domain containing proteins hold several domains, the actual number of PDZ proteins is closer to 180. Listed below are some of the better studied members of this family.
