Fungal cytoskeletal machinery

The fungal cytoskeletal machinery is a complex network of protein filaments and motor proteins essential for the growth, division, and pathogenicity of fungi. It primarily consists of microtubules (composed of alpha- and beta-tubulin), actin filaments, and motor proteins such as myosins, kinesins, and dyneins (Steinberg, G., 2007, Microbiology and Molecular Biology Reviews). These components facilitate critical processes including mitosis, intracellular transport of organelles, and the polarized growth of hyphae, which is a hallmark of invasive fungal infections (Sudbery, P. E., 2011, Nature Reviews Microbiology). Because the cytoskeleton is vital for maintaining cell shape and delivering cell wall-synthesizing enzymes to the growth tip, its disruption leads to growth arrest and cell death (Morris, N. R., 2006, Eukaryotic Cell). While some drugs like griseofulvin target fungal tubulin to inhibit mitosis, the high degree of conservation between fungal and human cytoskeletal proteins presents a significant challenge for achieving selective toxicity (Odds, F. C., 2003, Journal of Antimicrobial Chemotherapy). Recent research focuses on identifying divergent regions in fungal motor proteins or specific regulatory factors to develop more selective antifungal agents that minimize off-target effects in human hosts.
