Dissection of Arp2/3 complex actin nucleation mechanism and distinct roles for its nucleation-promoting factors in Saccharomyces cerevisiae.
Actin nucleation by the Arp2/3 complex is under tight control, remaining inactive until stimulation by nucleation-promoting factors (NPFs). Although multiple NPFs are expressed in most cell types, little is known about how they are coordinated and whether they perform similar or distinct functions. We examined genetic relationships among the four S. cerevisiae NPFs. Combining las17delta with pa...
متن کاملActin nucleation: Nucleation-promoting factors are not all equal
Arp2/3 complex plays a key role in regulated actin polymerization. A recent study has revealed marked differences in the ability of two nucleation-promoting factors - N-WASP and Scar/WAVE1 - to activate the Arp2/3 complex. Further insights have come from determination of the Arp2/3 crystal structure.
متن کاملOrdered nucleation and spreading of silenced chromatin in Saccharomyces cerevisiae.
In Saccharomyces cerevisiae, silencing at the HM loci depends on Sir proteins, which are structural components of silenced chromatin. To explore the structure and assembly of silenced chromatin, the associations of Sir proteins with sequences across the HMR locus were examined by chromatin immunoprecipitation. In wild-type cells, Sir2p, Sir3p, and Sir4p were spread throughout and coincident wit...
متن کاملDissection of Autophagosome Biogenesis into Distinct Nucleation and Expansion Steps
Rapamycin, an antifungal macrolide antibiotic, mimics starvation conditions in Saccharomyces cerevisiae through activation of a general G(0) program that includes widespread effects on translation and transcription. Macroautophagy, a catabolic membrane trafficking phenomenon, is a prominent part of this response. Two views of the induction of autophagy may be considered. In one, up-regulation o...
متن کاملMechanism and cellular function of Bud6 as an actin nucleation–promoting factor
Formins are a conserved family of actin assembly-promoting factors with diverse biological roles, but how their activities are regulated in vivo is not well understood. In Saccharomyces cerevisiae, the formins Bni1 and Bnr1 are required for the assembly of actin cables and polarized cell growth. Proper cable assembly further requires Bud6. Previously it was shown that Bud6 enhances Bni1-mediate...
