The PilZ protein family is named after the type IV pilus control protein first identified in Pseudomonas aeruginosa, expressed as part of the pil operon. It has a cytoplasmic location and is essential for type IV fimbrial, or pilus, biogenesis. PilZ is a c-di-GMP binding domain and PilZ domain-containing proteins represent the best studied class of c-di-GMP effectors. C-di-GMP, cyclic diguanosine monophosphate, the second messenger in cells, is widespread in and unique to the bacterial kingdom. Elevated intracellular levels of c-di-GMP generally cause bacteria to change from a motile single-cell state to a sessile, adhesive surface-attached multicellular state called biofilm.
