Warren's studies of the Golgi have yielded a rich trove of insights.

Report

p120 armadillo protein plakophilin 1 binds to eukaryotic translation factor eIF4A1, recruiting it into cap-binding complexes and stimulating translation.

When mitochondrial function fails, p53 is recruited to get rid of cyclin E, bringing mitotic progression to a halt.

The spindle matrix does not make a significant mechanical contribution to metaphase spindle length.

Loss of the condensin complex components Smc2 and -4 disrupts epigenetic modifications required for embryonic stem cell survival.

The L166P mutation in DJ-1 is associated with Parkinson’s disease. DJ-1–interacting protein BAG1 chaperones mutant DJ-1 and reverses its mutant phenotype.

Improving the efficiency of PrP translocation into the ER decreases levels of transmembrane bound protein and rescues mice from prion disease.

Evidence is presented for an unconventional protein secretion pathway that is conserved from yeast to Dictyostelium discoideum in which Acb1 may be sequestered into autophagosomal vesicles, which then fuse (either directly or indirectly) with the plasma membrane (see also the companion paper from Manjithaya et al. in this issue).

Evidence is presented for an unconventional protein secretion pathway that is conserved from yeast to Dictyostelium discoideum in which Acb1 may be sequestered into autophagosomal vesicles, which then fuse (either directly or indirectly) with the plasma membrane (see also the companion paper from Duran et al. in this issue).

Inhibitors of Na+/H+ exchange proteins block macropinocytosis by lowering the pH near the plasma membrane, which in turn inhibits actin remodeling by Rho family GTPases.

A proteomics approach identifies Drosophila Syd-1 as a Bruchpilot binding partner that controls maturation on both sides of the neuromuscular junction.

A specific glycosphingolipid regulates the E3 ubiquitin ligase Mindbomb1, which promotes the ligand endocytosis necessary for Notch activation.

Matrix-bound VEGF elicits more distinct vascular effects than soluble VEGF, including prolonged VEGFR2 activation with altered patterns of tyrosine activation and downstream enhancement of the p38/MAPK pathway.
