COP (coat protein) I-coated vesicles mediate intra-Golgi transport and retrograde from the Golgi to endoplasmic reticulum. These form through action of small GTPase ADP-ribosylation factor 1 (ARF1) COPI heptameric protein complex (coatomer), which consists seven subunits (α-, β-, β′-, γ-, δ-, ε- ζ-COP). In contrast mammals yeast, several isoforms for coatomer subunits, with exception γ δ, have been identified in Arabidopsis. To understand role proteins plant biology, we characterized a...
The early secretory pathway involves bidirectional transport between the endoplasmic reticulum (ER) and Golgi apparatus is mediated by coat protein complex I (COPI)-coated II (COPII)-coated vesicles. COPII vesicles are involved in ER to meanwhile COPI mediate intra-Golgi retrograde from ER. key component of coatomer complex, that composed seven subunits (α/β/β'/γ/δ/ε/ζ). In Arabidopsis two genes coding for β-COP subunit have been identified, which result recent tandem duplication. Here we...
Coat protein I (COPI) is necessary for intra-Golgi transport and retrograde from the Golgi apparatus back to endoplasmic reticulum. The key component of COPI coat coatomer complex, which composed seven subunits (α/β/β’/γ/δ/ε/ζ) recruited en bloc cytosol onto membranes. In mammals yeast, α- β’-COP WD40 domains mediate cargo-selective interactions with dilysine motifs present in canonical cargoes vesicles. contrast three isoforms (β’1-3-COP) have been identified Arabidopsis. To understand role...
