Fungal proteins with antiproliferative and anticancer activities.

: Fungi produce a variety of proteins with antiproliferative activity toward tumor cells and anticancer activity in tumor bearing mice. The aforementioned fungal proteins include ribonucleases, antifungal proteins, ubiquitin-like peptides, ribosome inactivating proteins, hemolysins, hemagglutinins/lectins, laccases, and protein-bound polysaccharopeptides.
