Deep mycosis is a severe fungal disease that could result in fatal outcomes. However, there is still a demand for highly effective and safe antifungal drugs, given the side effects of the existing treatments and the increase in the resistance to them. In this study, we evaluated the involvement of the lipid kinase Fab1 and its activator Vac14 (Fab1/Vac14) in tip growth in Saccharomyces cerevisiae INVSc1, along with their impact on cell proliferation, using a genetic approach to inhibit them. The results revealed that Fab1/Vac14 inhibition suppressed growth and caused an increase in the rate of β-1,3-glucanase (BGL2) fused with emerald green fluorescent protein (EmGFP) (BGL2-EmGFP) localization at the tip. The inhibition of the endocytic pathway using a lysosome inhibitor also resulted in an increased localization of BGL2-EmGFP at the tip. The overexpression of wild-type BGL2-EmGFP, but not that of the inactive mutant BGL2, led to a complete loss of the cell proliferation ability. These findings suggested that the Fab1/Vac14 complex could be a novel target for the development of antifungal drugs based on tip growth regulation, possibly via excessive cell wall degradation.
