THE EFFECT OF METAL BINDING ON THE STRUCTURE OF ANNEXIN V AND IMPLICATIONS FOR MEMBRANE BINDINGTHE EFFECT OF METAL BINDING ON THE STRUCTURE OF ANNEXIN V AND IMPLICATIONS FOR MEMBRANE BINDING
Structural highlights
Disease[ANXA5_HUMAN] Defects in ANXA5 are associated with susceptibility to pregnancy loss, recurrent, type 3 (RPRGL3) [MIM:614391]. A common complication of pregnancy, resulting in spontaneous abortion before the fetus has reached viability. The term includes all miscarriages from the time of conception until 24 weeks of gestation. Recurrent pregnancy loss is defined as 3 or more consecutive spontaneous abortions.[1] Function[ANXA5_HUMAN] This protein is an anticoagulant protein that acts as an indirect inhibitor of the thromboplastin-specific complex, which is involved in the blood coagulation cascade. Evolutionary Conservation Check, as determined by ConSurfDB. You may read the explanation of the method and the full data available from ConSurf. Publication Abstract from PubMedThe structure of annexin V, crystallised in the presence of two calcium or barium ions for each protein molecule, was solved by molecular replacement to 0.24 nm resolution. The two metal ions are found in domains I and IV, i.e. on the same side of the channel that lies in the centre of the molecule. The structures of the barium and calcium form are extremely close, the only differences localised in the metal-binding sites that lie on the surface of the molecule. The occupancies of the metal ions, however, are lower for barium than for calcium, expressing the lower affinity of the protein for the former. The packing of the annexin molecules in the crystal asymmetric unit may represent a model for the calcium driven association of membrane-bound annexins that leads to membrane fusion. The effect of metal binding on the structure of annexin V and implications for membrane binding.,Lewit-Bentley A, Morera S, Huber R, Bodo G Eur J Biochem. 1992 Nov 15;210(1):73-7. PMID:1446685[2] From MEDLINE®/PubMed®, a database of the U.S. National Library of Medicine. References
