“…It has long been assumed that coacervation of tropoelastin is a crucial step in assembly of the elastic fiber (42)(43)(44). Our data suggest, however, that coacervation may not be involved in the initial steps of elastin assembly and that coacervation by itself cannot drive elastin assembly in tissues.…”

“…Coacervation, an entropically driven, inverse temperature transition caused by the interaction of the hydrophobic domains in the molecule, occurs as tropoelastin monomers associate to form large aggregates. Several laboratories have shown that the large hydrophobic sequences in the middle of the molecule play a dominant role in the intermolecular interactions that occur during coacervation (43). If coacervation were the only requirement for assembly, then all of our deletion constructs would form fibers (or at least aggregates) because they all contain the critical middle hydrophobic sequences.…”

“…Monomeric elastin, called tropoelastin, is secreted from the cell as a soluble protein. Isolated and purified tropoelastin has been shown to exhibit a great tendency to aggregate (coacervation) in physiological solution and at temperatures in the physiological range, giving rise to supramolecular structures very similar to those found in natural elastic fibers (4,5,11). This self-aggregation property of tropoelastin is thought to contribute to elastic fiber assembly in vivo.…”

“…Through coacervation, tropoelastin molecules were thought to be converted from molecules largely lacking secondary and tertiary structure to a more ordered state (2,7,9,10). Electron micrographs show parallel arrays of 5-nm-wide filaments of tropoelastin coacervates that are similar to the fibrous structure of mature elastin (3,4,11). The importance of coacervation in the formation of lysine cross-links has been shown in smooth muscle cells where culturing at temperatures below 37°C hampers elastin formation (12,13).…”
