Supplementary information

Annexin-4 also known as ANXA4 is a protein with a molecular mass of approximately 36 kDa. It belongs to the annexin family characterized by their ability to bind phospholipids in a calcium-dependent manner. Annexin-4 is widely expressed in various tissues including epithelial cells in the gastrointestinal tract kidney and placenta. This protein associates with the inner surface of the plasma membrane and plays roles in processes like vesicle trafficking and membrane dynamics.

Biological function summary

The protein functions in cellular processes involving membrane-related activities. It does not appear to be part of a larger stable complex but researchers have observed its interaction with cell membranes and involvement in membrane repair and cell signal transduction. Annexin-4 can mediate interactions between the cytoskeleton and the plasma membrane impacting cell motility and structure.

Pathways

Annexin-4 functions in the phospholipid signaling pathways particularly influencing pathways related to calcium signaling. In the calcium-dependent signaling pathway Annexin-4 regulates cellular responses by cooperating with proteins such as calmodulin and other annexins contributing to processes like cell proliferation and apoptosis.

Annexin-4 has shown associations with cancer and inflammatory diseases. Abnormal expression of Annexin-4 has been observed in certain cancer types where it may affect tumor metastasis and progression by modifying cellular adhesion and migration. Additionally its interactions with inflammation-related proteins such as interleukins suggest its involvement in inflammatory responses and disorders like inflammatory bowel disease. Researchers continue to explore its potential as a biomarker for early detection and as a target for therapeutic intervention.
