Secreted alkaline protease that allows assimilation of proteinaceous substrates. Acts as a significant virulence factor in invasive aspergillosis. Involved in immune evasion from the human and mice complement systems during infection. Efficiently cleaves important components of the complement cascade such as such as C3, C4, C5, and C1q, as well as IgG, which leads to down-regulation of complement activation at the hyphal surface. Recombinant protein corresponding to aa102-403 from Neosartorya fumigata Alkaline protease 1, fused to 10X His-Tag at N-terminal and Myc-Tag at C-terminal, expressed in E. coli.
