Table 1. Major phospholipid (PL)-binding proteins.
Protein | Size | Location | Description |
---|---|---|---|
Annexins | 36 kd, 70 aa, repeats in α − helix | II: cell granules, membranes, rafts V: placenta | Ca 2+ -dependent PL binding; II binds S100A10, t-PA |
β 2 -Glycoprotein I | 48 kd, 326 aa | Plasma: 200 µg/mL | Multimer; circular form assumes J-shape when bound to PL |
Cardiolipin | 1,466 g/mol | Mitochondrial inner membrane | Diphosphatidyl glycerol; structural integrity of respiratory chain |
Vimentin | 310 aa-polymerizes | Skin and other organs; cell surface and extracellular matrix | Phosphorylated filamentous protein |
Abbreviations: aa, amino acids; t-PA, tissue plasminogen activator.
