|Description :||Annexin IV (ANX4) belongs to the annexin family of calcium-dependent phospholipid binding proteins. Although their functions are still not clearly defined, several members of the annexin family have been implicated in membrane-related events along exocytotic and endocytotic pathways. ANX4 has 45 to 59% identity with other members of its family and shares a similar size and exon-intron organization. Isolated from human placenta, ANX4 encodes a protein that has possible interactions with ATP, and has in vitro anticoagulant activity and also inhibits phospholipase A2 activity. ANX4 is almost exclusively expressed in epithelial cells. Several transcript variants encoding different isoforms have been found for this gene.|

Q&As (17)Ask a question
Yes, ANXA4 has been shown to interact with several proteins and lipids. It can bind to phospholipids such as phosphatidylserine and phosphatidylinositol, which are important for its membrane association. ANXA4 can also interact with other annexin proteins or cytoskeletal proteins, potentially contributing to its diverse cellular functions.
The expression of ANXA4 can be regulated by various factors, including cellular differentiation, hormones, and cytokines. Additionally, it can be influenced by environmental factors, such as changes in calcium levels and cellular stress.
Yes, ANXA4 can undergo post-translational modifications such as phosphorylation and acetylation. These modifications can affect the protein's stability, subcellular localization, and interactions with other molecules, potentially modulating its cellular functions.
ANXA4 has been implicated in several diseases and conditions. It has been linked to the pathogenesis of atherosclerosis, where it plays a role in lipid metabolism and plaque formation. ANXA4 has also been associated with certain cancers, such as gastric cancer and breast cancer, where it may influence tumor growth and metastasis.

These genetic alterations may contribute to individual differences in ANXA4 expression or function, potentially impacting disease susceptibility or progression. Further research is needed to fully understand the significance of these genetic variations.
Yes, ANXA4 appears to play a role in cell adhesion and migration. It has been associated with the regulation of focal adhesions and actin cytoskeleton dynamics, processes crucial for cell movement and tissue remodeling. ANXA4 may modulate these processes through its interaction with cytoskeletal components and signaling pathways.
ANXA4 has shown potential as a diagnostic or prognostic marker in certain diseases. For example, its expression levels have been correlated with clinical outcomes in breast cancer and ovarian cancer. However, more research is needed to validate its utility and establish standardized protocols for its use as a diagnostic or prognostic marker in different contexts.
Genetic variants and mutations in ANXA4 have been reported in certain individuals. These variants can occur in the coding sequence of the gene and may lead to alterations in the protein structure or function. Studies investigating the functional impact of these genetic variants and their association with specific diseases are still ongoing.
ANXA4 has the ability to bind calcium ions, and this binding triggers conformational changes in the protein that allow it to interact with other molecules or membranes. These calcium-dependent interactions are essential for the regulation of various cellular processes, including vesicle fusion, exocytosis, and intracellular signaling.
Yes, the ANXA4 protein is evolutionarily conserved and found in many species, including mammals, birds, reptiles, and fish. The high degree of conservation suggests its important biological functions across different organisms.
