... of this specialized form of polarized growth. Furthermore, as previously demonstrated for Dnf1 and Dnf2p, the phospholipid flipping activity of Dnf3p is positively regulated by flippase kinase 1 (Fpk1p) and Fpk2p. Phylogenetic analyses demonstrate that Dnf3p belongs to a subfamily of P4 ATPases specific for fungi...

.... In particular, phosphatidylinositol 4,5-bisphosphate [PtdIns(4,5) P 2 ] has essential roles in polarized growth as well as in cellular responses to stress. In the yeast Saccharomyces cerevisiae , the sole phosphatidylinositol-4-phosphate 5-kinase (PI4P5K) Mss4p is essential for generating plasma membrane PtdIns...

... of Bck1p for the MAP kinase module of the CWIP. The measured interaction with Spa2p suggests that Bck1p also localizes to sites of polar growth ( van Drogen and Peter, 2002 ). Indeed, the natively expressed Bck1-GFP can be detected at the tips of small buds ( Fig. 2B ). However, the most prominent staining...

.... This behavior of CaBnr1p may play a key role in correcting Cabni1 Δ defects during hyphal growth. Cabni1 Δ exhibited reduced virulence in mice. These results indicate that the formins play an important role in Candida albicans polarized growth and CaBni1p's function is required for virulence. * Author...

...Juan Carlos G. Cortés; Junpei Ishiguro; Angel Durán; Juan Carlos Ribas Schizosaccharomyces pombe Bgs1p/Cps1p has been identified as a putative (1,3)β-D-glucan synthase (GS) catalytic subunit with a possible function during cytokinesis and polarized growth. To study this possibility,double mutants...
