During cilium-generated signaling, ciliary membrane protein trafficking is unidirectional and ciliary membrane protein composition is regulated through action in the cytoplasm of the retrograde intraflagelllar transport (IFT) motor and shedding of ciliary ectosomes.

In Drosophila oocytes, the exclusion of the scaffold protein PAR3 from the posterior cortex depends on PAR1 and endocytosis, while its anterior localisation requires microtubules and recycling endosomes.

A Notch-mediated signaling pathway upregulates a Sec14-GOLD phosphopholipid binding protein that promotes a morphogenetic process important in tissue remodeling and renewal.

A missing link between the AP complexes and COPI sheds light on the evolution of vesicle coat proteins and trafficking pathways in the earliest eukaryotes.

COPI vesicle coat protein recognizes a ubiquitin sorting signal on an exocytic v-SNARE to mediate recycling.

Ser57 phosphorylation regulates ubiquitin homeostasis by inhibiting deubiquitylase-mediated recycling and promoting vacuolar degradation.

A novel microscopy-based assay shows that dendritic cells encountering pathogenic stimuli form increased complexes of specific SNARE proteins, driving release of large amounts of inflammatory cytokines.

Evidence that certain proteins can be transported between Golgi via structures that resemble COPI vesicles suggests that these vesicles could also be involved in the transport of proteins from the cis to the trans face of the Golgi.

Oxidative stress leads to the translocation of Rab5 from endosome to mitochondria, regulated by ALS/Alsin, a component associated with amyotrophic lateral sclerosis, leading to mitochondrial-endosomal physical contacts and a cytoprotective response.

Rather than relying on intrinsic intracellular targeting information, the key phototransduction enzyme guanylate cyclase 1 is delivered to the photosensory cilium with the visual pigment rhodopsin.
