| Abstract: | A calcium binding protein of Mr = 54,000 has been isolated from human blood platelets. This protein has been shown to enhance Ca2+-induced aggregation of phosphatidylserine liposomes, suggesting that it may be a member of a recently recognized class of binding proteins known to interact with phospholipids and the membrane in a Ca2+ dependent manner. Because of the "synexin-like" activity of this protein it may be involved in Ca2+ regulated platelet secretion as well as cell motility. |
