GCC185, a trans-Golgi network-localized protein predicted to assume a long, coiled-coil structure, is required for Rab9-dependent recycling of mannose 6-phosphate receptors (MPRs) to the Golgi and for microtubule nucleation at the Golgi via CLASP proteins. GCC185 localizes to the Golgi by cooperative interaction with Rab6 and Arl1 GTPases at adjacent sites(More)
Neutrophils are the most abundant white blood cells in circulation, and patients with congenital neutrophil deficiencies suffer from severe infections that are often fatal, underscoring the importance of these cells in immune defense. In spite of neutrophils' relevance in immunity, research on these cells has been hampered by their experimentally(More)
Pore progress: Oxford Nanopore's modified nanopore can distinguish between the four standard DNA nucleotides and methylated cytosine. The aim is to use an endonuclease (green) to feed the nucleotides to the pore one by one. (Photo: iemedia solutions.) Coming soon to a doctor's surgery near you? Hopes placed on the sequencing of 'the' human genome and the(More)
The chemokine family forms two different types of homodimer despite members sharing nearly identical folds. To study the formation of quaternary structure in this family, rational mutagenesis was employed on a representative member of each subfamily (MIP-1beta and IL-8). The variants were studied by analytical ultracentrifugation and NMR, and it was(More)
A new paper from Campellone et al. in a recent issue of Cell identifies WHAMM, a multifunctional protein that stimulates Arp2/3-mediated actin polymerization, binds and organizes microtubules, and influences the structure and efficiency of the Golgi complex. WHAMM's membrane localization at the entry face of the Golgi complex is novel for an actin(More)
