Supplementary information

The COPE protein also known as Coatomer Protein Complex Subunit E is a component of the COPI coatomer complex. This protein roughly weighs approximately 34 kDa and is present in the Golgi apparatus where it takes part in vesicle formation processes. COPE is expressed in numerous cell types highlighting its importance in intracellular transport mechanisms and maintaining cellular organization.
Biological function summary

COPE plays a significant role in the retrograde transport of proteins from the Golgi back to the endoplasmic reticulum being part of the larger COPI complex. The COPI coatomer complex operates in conjunction with other coat proteins like clathrin to ensure vesicle trafficking and membrane dynamics. This mechanism is essential for membrane recycling protein sorting and other cellular logistics.

Pathways

COPE is important in the secretory pathway. It interacts closely with other components like ARF1 a small GTPase that regulates coat assembly and disassembly to maintain efficient protein sorting. Moreover COPE's role intersects with the ER-to-Golgi transport pathway acting alongside proteins like Sec27 demonstrating its connection within a tightly regulated trafficking network essential for cellular function.

COPE’s malfunction associates with neurodegenerative diseases. Disruption in its role in vesicular trafficking can lead to protein aggregation disorders like Alzheimer's disease where protein accumulation becomes pathogenic. COPE interaction with proteins such as APP (Amyloid Precursor Protein) becomes evident in the pathology of Alzheimer's showcasing its importance in disease progression.

General info

Function

The coatomer is a cytosolic protein complex that binds to dilysine motifs and reversibly associates with Golgi non-clathrin-coated vesicles, which further mediate biosynthetic protein transport from the ER, via the Golgi up to the trans Golgi network. The coatomer complex is required for budding from Golgi membranes, and is essential for the retrograde Golgi-to-ER transport of dilysine-tagged proteins. In mammals, the coatomer can only be recruited by membranes associated with ADP-ribosylation factors (ARFs), which are small GTP-binding proteins; the complex also influences the Golgi structural integrity, as well as the processing, activity, and endocytic recycling of LDL receptors (By similarity).

Sequence similarities

Belongs to the COPE family.

Post-translational modifications

Phosphorylated by PKA.. Polyubiquitinated by RCHY1 in the presence of androgen, leading to proteasomal degradation.
