Viral and Host Factors Regulating HIV-1 Envelope Protein Trafficking and Particle Incorporation by Boris Anokhin, Paul Spearman

“…Env follows an unusual pathway to arrive at the site of particle assembly, first traversing the secretory pathway to the plasma membrane (PM), then undergoing endocytosis, followed by directed sorting to the site of particle assembly on the PM. …”

Ubiquitin-mediated degradation at the Golgi apparatus by Lana Buzuk, Doris Hellerschmied

“…The Golgi apparatus is an essential organelle of the secretory pathway in eukaryotic cells. It processes secretory and transmembrane proteins and orchestrates their transport to other endomembrane compartments or the plasma membrane. …”

Manipulation of the Host Endomembrane System by Bacterial Effectors by Hyelim Jeon, Cécile Segonzac

“…We further focus on Pseudomonas syringae, Xanthomonas spp., and Ralstonia solanacearum type III secreted effectors that one or both localize to and associate with components of the host endomembrane system or the cytoskeleton network to highlight the diversity of virulence strategies deployed by bacterial pathogens beyond the inhibition of the secretory pathway.

A rab1 GTPase is required for transport between the endoplasmic reticulum and golgi apparatus and for normal golgi movement in plants. by Batoko, H, Zheng, H, Hawes, C, Moore, I

“…We describe a green fluorescent protein (GFP)-based assay for investigating membrane traffic on the secretory pathway in plants. Expression of AtRab1b(N121I), predicted to be a dominant inhibitory mutant of the Arabidopsis Rab GTPase AtRab1b, resulted in accumulation of a secreted GFP marker in an intracellular reticulate compartment reminiscent of the endoplasmic reticulum. …”

Novel membrane traffic steps regulate the exocytosis of the Menkes disease ATPase. by Cobbold, C, Ponnambalam, S, Francis, M, Monaco, A

“…The Menkes disease protein (ATP7A or MNK) is a P-type transmembrane ATPase that regulates translocation of cytosolic copper ions across intracellular membranes of compartments along the secretory pathway. In this study, we show that endogenous MNK in cultured cell lines is localized to the distal Golgi apparatus and translocates to the plasma membrane in response to exogenous copper ions. …”

Phosphorylation of iRhom2 at the plasma membrane controls mammalian TACE-dependent inflammatory and growth factor signalling. by Grieve, A, Xu, H, Künzel, U, Bambrough, P, Sieber, B, Freeman, M

“…Here, we reveal that iRhom2 remains associated with TACE throughout the secretory pathway, and is stabilised at the cell surface by this interaction. …”

Restricted processing of glycans by endomannosidase in mammalian cells. by Kukushkin, N, Easthope, I, Alonzi, D, Butters, T

“…Removal of α-glucose residues from nascent glycoproteins in the early secretory pathway is a requirement for further N-glycan maturation. …”

Toxoplasma gondii Syntaxin 6 is required for vesicular transport between endosomal-like compartments and the Golgi complex. by Jackson, A, Clucas, C, Mamczur, N, Ferguson, D, Meissner, M

“…It therefore appears that Toxoplasma has retained a plant-like secretory pathway.…”

OS-9 and GRP94 deliver mutant alpha1-antitrypsin to the Hrd1-SEL1L ubiquitin ligase complex for ERAD. by Christianson, J, Shaler, T, Tyler, R, Kopito, R

“…Terminally misfolded or unassembled proteins in the early secretory pathway are degraded by a ubiquitin- and proteasome-dependent process known as ER-associated degradation (ERAD). …”

Quantitative analysis of plant ER architecture and dynamics by Hawes, C, Kriechbaumer, V, Pain, C, Kittlemann, M, Fricker, M

“…The endoplasmic reticulum (ER) is a highly dynamic polygonal membrane network composed of interconnected tubules and sheets (cisternae) that forms the first compartment in the secretory pathway involved in protein translocation, folding, glycosylation, quality control, lipid synthesis, calcium signalling, and metabolon formation. …”

Expression and analysis of the glycosylation properties of recombinant human erythropoietin expressed in Pichia pastoris by Teh, Ser Huy, Fong, Mun Yik, Mohamed, Zulqarnain

“…The entire recombinant human erythropoietin (rhEPO) gene was constructed using the Splicing by Overlap Extension by PCR (SOE-PCR) technique, cloned and expressed through the secretory pathway of the Pichia expression system. Recombinant erythropoietin was successfully expressed in P. pastoris. …”

Loss of hypothalamic Furin affects POMC to proACTH cleavage and feeding behavior in high-fat diet-fed mice by Ilaria Coppola, Bas Brouwers, Leanne Walker, Ceyhun Alar, Sandra Meulemans, Anne White, Bruno Ramos-Molina, John W.M. Creemers

“…Importantly, we found that in vitro, the first stage in processing where POMC is cleaved into proACTH was achieved by FURIN but not by PC1/3 or the other proprotein convertases in cell lines lacking a regulated secretory pathway. Conclusions: These results suggest that FURIN processes POMC into proACTH before sorting into the regulated secretory pathway, challenging the dogma that PC1/3 and PC2 are the only convertases responsible for POMC cleavage. …”

The EGF repeat-specific O-GlcNAc-transferase Eogt interacts with notch signaling and pyrimidine metabolism pathways in Drosophila. by Reto Müller, Andreas Jenny, Pamela Stanley

“…The O-GlcNAc transferase Eogt modifies EGF repeats in proteins that transit the secretory pathway, including Dumpy and Notch. In this paper, we show that the Notch ligands Delta and Serrate are also substrates of Eogt, that mutation of a putative UDP-GlcNAc binding DXD motif greatly reduces enzyme activity, and that Eogt and the cytoplasmic O-GlcNAc transferase Ogt have distinct substrates in Drosophila larvae. …”
