WebNov 14, 2008 · Septins are an evolutionarily conserved group of GTP-binding and filament-forming proteins that were originally discovered in yeast. Once the preserve of a small band of yeast biologists, the field has grown rapidly in the past few years and now encompasses the whole of animal and fungal biology. Furthermore, septins are nowadays recognized … WebThe septins undergo cell cycle depending transitions: In G1 phase active Cdc42 (dark blue) polarizes at the plasma membrane, defining the presumptive bud site. The septins (dark green) are recruited to this site and remain as a ring at the neck upon bud emergence. This ring expands into a stable hourglass-shaped collar until the onset of mitosis.
