PDZ domain proteins: scaffolds for signaling complexes

Curr Biol. 1997 Dec 1;7(12):R770-3. doi: 10.1016/s0960-9822(06)00401-5.

Abstract

InaD, a Drosophila photoreceptor scaffolding protein, assembles multiple signal-transducing proteins at the membrane via its five PDZ domains, enhancing speed and efficiency of vision. Extensive conservation of PDZ domains suggests that these motifs have a general role in organizing diverse signaling complexes.
