The domain also occurs in a Dictyostelium prespore-cell-inducing factor Psi and in fibrocystin, the mammalian protein whose mutation leads to polycystic kidney and hepatic disease. The crystal structure of PA shows that this domain (named PA14 after its location in the PA20 pro-peptide) has a beta-barrel structure. The PA14 domain sequence suggests a binding function, rather than a catalytic role. The PA14 domain distribution is compatible with carbohydrate binding.

It is involved in the first step of toxin entry into host cells, enabling lethal factor (LF) and oedema factor (EF) to cross to the cytosol. PA undergoes cleavage by Furin to generate PA20 and PA63. The latter, which adopts a ring-shaped heptameric assembly, shows four distinct domains. The fourth domain, a carboxy- terminal receptor-binding domain, shows an initial hairpin and helix, followed by a beta-sandwich with an immunoglobulin-like fold (this entry) [1-5].
