The 14-3-3 family of proteins function as small adaptors that facilitate a diverse array of cellular processes by mediating specific protein interactions. One such process is the DNA damage checkpoint, where these proteins prevent inappropriate activation of cyclin-dependent kinases. The filamentous fungus Aspergillus nidulans possesses a highly conserved 14- 3-3 homologue (artA) that may function in an analogous manner to prevent septum formation. However, instead of blocking septation, over-expression of artA causes a severe delay in the polarization of conidiospores. This observation suggests that these proteins play an important role in hyphal morphogenesis.
