Pb18 Cbp1 is highly expressed in Paracoccidioides Pb18 yeast cells [60] and Pb03 Cbp1 is capable of triggering host-cell lysis when expressed in the Hc G217B cbp1 mutant background, but whether any Paracoccidioides species utilize Cbp1 during infection is yet to be determined. The gene discussed is SERPINH1; the disease is infection.
