Identification of the switch in early-to-late endosome transition.
Poteryaev D, Datta S, Ackema K, Zerial M, Spang A. Poteryaev D, et al. Cell. 2010 Apr 30;141(3):497-508. doi: 10.1016/j.cell.2010.03.011. Cell. 2010. PMID: 20434987
The transition between early and late endosomes could be mediated either through transport carriers or by Rab conversion, a process in which the loss of Rab5 from an endosome occurs concomitantly to the acquisition of Rab7. ...SAND-1/Mon1 thus acts as a switch by co …

Involvement of the actin cytoskeleton and homotypic membrane fusion in ER dynamics in Caenorhabditis elegans.

Septin-dependent compartmentalization of the endoplasmic reticulum during yeast polarized growth.
Luedeke C, Frei SB, Sbalzarini I, Schwarz H, Spang A, Barral Y. Luedeke C, et al. J Cell Biol. 2005 Jun 20;169(6):897-908. doi: 10.1083/jcb.200412143. J Cell Biol. 2005. PMID: 15967812 Free PMC article.
Although a soluble protein diffused rapidly throughout the ER lumen, diffusion of ER membrane proteins was restricted at the bud neck. ...The membrane-associated protein Bud6 localized to the bud neck in a septin-dependent manner and was required to restrict the dif …

The terminal phase of cytokinesis in the Caenorhabditis elegans early embryo requires protein glycosylation.
Wang H, Spang A, Sullivan MA, Hryhorenko J, Hagen FK. Wang H, et al. Mol Biol Cell. 2005 Sep;16(9):4202-13. doi: 10.1091/mbc.e05-05-0472. Epub 2005 Jun 29. Mol Biol Cell. 2005. PMID: 15987734 Free PMC article.
However, embryos deficient in N-glycosylation exhibited a variable inability to complete cytokinesis. The most potent block in early embryonic cell division was obtained by RNAi of the polypeptide xylose transferase (ppXyl-T), which is required to initiate the proteoglycan …

Closing the GAP between polarity and vesicle transport.
Macara IG, Spang A. Macara IG, et al. Cell. 2006 May 5;125(3):419-21. doi: 10.1016/j.cell.2006.04.011. Cell. 2006. PMID: 16678084 Review.
In this issue of Cell, Wells et al. (2006) provide intriguing evidence for a new pathway that links polarity proteins and vesicle transport to the maintenance of tight junctions, through the control of Cdc42 by Rich1, a GTPase-activating protein....

Interaction of SNAREs with ArfGAPs precedes recruitment of Sec18p/NSF.
Schindler C, Spang A. Schindler C, et al. Mol Biol Cell. 2007 Aug;18(8):2852-63. doi: 10.1091/mbc.e06-08-0756. Epub 2007 May 23. Mol Biol Cell. 2007. PMID: 17522384 Free PMC article.
We previously found that ADP-ribosylation factor GTPase activating proteins (ArfGAPs) promoted a conformational change on SNAREs that allowed recruitment of the small GTPase Arf1p in stoichiometric amounts. ...Here again, the induction of a conformational change by …
