MSH: Family of calcium- and phospholipid-binding proteins which are structurally related and exhibit immunological cross-reactivity. Each member contains four homologous 70-kDa repeats. The annexins are differentially distributed in vertebrate tissues (and lower eukaryotes) and appear to be involved in MEMBRANE FUSION and SIGNAL TRANSDUCTION.,CSP: family of proteins which bind phospholipids in the presence of calcium, believed to mediate intracellular calcium's role in membrane fusion and related events such as exocytosis; lipocortin and endonexin may also function extracellularly as inhibitors of phospholipase and blood coagulation.
