RAT ANNEXIN V COMPLEXED WITH GLYCEROPHOSPHOETHANOLAMINE
|
OverviewOverview
Structural evidence is presented for a 'Ca(2+)-bridging' mechanism, proposed for Ca(2+)-binding interfacial membrane proteins such as, annexins, protein kinase C, and certain coagulation proteins. Crystal, structures of Ca(2+)-annexin V complexes with phospholipid polar heads, provide molecular details of 'Ca(2+)-bridges' as key features in the, membrane attachment exhibited by these proteins. Distinct binding sites, for phospholipid head groups are observed, including a novel, double-Ca2+, recognition site for phosphoserine that may serve as a phosphatidylserine, receptor site in vivo.
