CP homologs are also found in both the Ascomycota and the Basidiomycota branches of Dikarya.
[1] This toxin causes the severe plant disease: canker stain.
This protein occurs in the cell wall of the fungus and is involved in the host-pathogen interaction and induces both cell necrosis and phytoalexin synthesis which is one of the first plant defense-related events.
[2] CP is a 120 amino acid protein, containing 40% hydrophobic residues.
The N-terminal region of CP is very similar to cerato-ulmin, a phytotoxic protein produced by the Ophiostoma species belonging to the hydrophobin family, which also self-assembles.
