Function

Calcium-regulated membrane-binding protein whose affinity for calcium is greatly enhanced by anionic phospholipids. It binds two calcium ions with high affinity. May be involved in heat-stress response. Inhibits PCSK9-enhanced LDLR degradation, probably reduces PCSK9 protein levels via a translational mechanism but also competes with LDLR for binding with PCSK9 (PubMed:18799458, PubMed:22848640, PubMed:24808179). (Microbial infection) Binds M.pneumoniae CARDS toxin, probably serves as one receptor for this pathogen. When ANXA2 is down-regulated by siRNA, less toxin binds to human cells and less vacuolization (a symptom of M.pneumoniae infection) is seen.

Activity summary

Annexin-2 also known as ANXA2 is a multifunctional protein of approximately 36 kDa. It belongs to the annexin family and is known for its strong calcium-dependent interactions with phospholipid membranes. Commonly expressed in endothelial cells it also appears in various tissues including epithelial cells and certain types of cancer cells. ANXA2 forms a heterotetramer complex with S100A10 also known as p11 which modulates its availability and function. Other names for ANXA2 include its gene designation M298 and its role in complexes often goes by ANXA2R.

Biological function summary

Annexin-2 acts beyond mere cellular structural support. It plays a part in fibrinolysis by acting as a co-receptor for plasminogen and tissue plasminogen activator promoting plasmin generation. The protein is also implicated in membrane trafficking signal transduction and organization of microdomains on cellular surfaces. As part of a complex with S100A10 ANXA2 can bind to cytoskeletal elements facilitating vesicle trafficking and influencing cell shape and motility. This complex assembly hints at ANXA2's importance in maintaining cellular dynamism and interplay with external signals.

Pathways

ANXA2 is integral in the regulation of the plasminogen activation pathway important for fibrinolytic activity. It also participates in the signal transduction pathways influencing cellular responses to stress and growth factors. ANXA2 interacts with various proteins like Src kinase and is involved in processes like the EGFR signaling pathway. This protein often crosstalks with the cytoskeletal network enabling the coupling of membrane dynamics with intracellular signaling cascades.

Associated diseases and disorders

Annexin-2's dysregulation associates with conditions such as cancer and thrombosis. In cancer overexpression of ANXA2 links with tumor progression invasion and metastasis acting synergistically with proteins like Src to promote oncogenic pathways. In thrombosis ANXA2’s role in fibrinolysis becomes impaired contributing to excessive clot formation. Studies also indicate interactions with plasminogen-related proteins as being central to understanding its pathological roles in these diseases.

    Immunohistochemistry (Formalin/PFA-fixed paraffin-embedded sections) - HRP Anti-Annexin-2/ANXA2 antibody [EPR13052(B)] (ab200798)

    IHC image of Annexin-2/ANXA2 staining in a section of formalin-fixed paraffin-embedded human prostate tissue (normal)*, performed on a Leica BOND. The section was pre-treated using heat mediated antigen retrieval with sodium citrate buffer (pH6, epitope retrieval solution 1) for 20mins. The section was then incubated with ab200798, 1/100 dilution, for 15 mins at room temperature. DAB was used as the chromogen. The section was then counterstained with haematoxylin and mounted with DPX. The inset negative control image is taken from an identical assay without primary antibody.

    For other IHC staining systems (automated and non-automated) customers should optimize variable parameters such as antigen retrieval conditions, primary antibody concentration and antibody incubation times.

    This blot was produced using a 4-12% Bis-tris gel under the MOPS buffer system. The gel was run at 200V for 50 minutes before being transferred onto a Nitrocellulose membrane at 30V for 70 minutes. The membrane was then blocked for an hour using 3% milk before being incubated with ab200798 overnight at 4°C. Antibody binding was visualised using ECL development solution ECL Substrate Kit (High Sensitivity) ab133406.
