Tropoelastin is a low complexity protein on both primary and secondary sequence levels. Nature 451, 977980. Mol. This suggests a high level of conformational sampling during this phase of coacervation, indicating that the flexibility of tropoelastin plays a key role in assembly that may persist, to some extent, into later stages of assembly (Reichheld et al., 2020).

Structural analysis of photocrosslinkable methacryloyl-modified protein derivatives. Elastin is heterogeneously cross-linked. Biol. Baul, U., Bley, M., and Dzubiella, J. Positively charged lysine residues in domains 17 were identified to interact with negatively charged HS, most likely via ionic interactions (Lee et al., 2017). While the clinical stage tropoelastin platform provides multiple opportunities for aesthetics, scar remodelling and tissue repair, it also has the . (2020). Furthermore, as integrins are involved in the remodeling of the ECM (Bonnans et al., 2014), this is consistent with a model where the tropoelastin-integrin interaction forms part of the wound repair process. J. Biol. Characterization of the complete human elastin gene. The business could generate net sales of approximately $7 to $8 billion in 2025 from $3.8 billion in 2017. This phenomenon is supported by in vitro peptide studies, which note that increasing the space between PG motifs or removing prolines results in more ordered structures (Rauscher et al., 2006). Biopolymers 103, 563573. doi: 10.1021/acs.biomac.8b01503, Rauscher, S., Baud, S., Miao, M., Keeley, F. W., and Poms, R. (2006). The cross-linking domains are defined by lysines, which are responsible for the formation of durable bi-, tri-, and tetrafunctional cross-links within mature elastin. 286, 35943610. Due to the lack of a full-atomistic structure, a number of elastin derivatives, including isolated tropoelastin domains (Toonkool et al., 2001; Mackay et al., 2005; Dyksterhuis et al., 2007; Dyksterhuis and Weiss, 2010) and synthetic elastin-derived peptides (EDPs) (Luan et al., 1990; Tamburro et al., 1992; Kentsis and Sosnick, 1998; Kumashiro et al., 2006; Reichheld et al., 2014, 2017; Muiznieks et al., 2015; MacEwan et al., 2017; Tarakanova et al., 2017) have been studied to understand tropoelastins domain level properties. doi: 10.1016/j.jsb.2005.02.005, Martin, S. L., Vrhovski, B., and Weiss, A. S. (1995). Tropoelastin is an ECM component primarily located in elastic tissues and has been shown to promote the expansion of hematopoietic stem cells (HSCs) and MSCs when used as a substrate coating or as part of the substrate bulk material ().The ECM is proposed to modulate stem cell phenotype and activity, including proliferation, via its chemistry, topography, and mechanical properties (). In addition to its involvement in molecular elasticity, the flexibility of tropoelastin also a key requirement for self-assembly into elastin, with mutations that perturb this having detrimental effects on tissue (Yeo et al., 2016, 2017). Chem. Tropoelastin bridge region positions the cell-interactive C terminus and contributes to elastic fiber assembly. doi: 10.1002/mabi.201800250, Tiedemann, K., Batge, B., Muller, P. K., and Reinhardt, D. P. (2001). (2019). 1862, 324334. Med. A., Starcher, B. C., and Urry, D. W. (1974). Solving tropoelastins global structure (Baldock et al., 2011) allowed for 3D mapping on tropoelastin of the approximate locations of domains 10, 19, and 25, which were the first unequivocally cross-linked domains to be discovered (Brown-Augsburger et al., 1995). Elastic fibers provide tissues with mechanical resilience, durability, and cell interactivity, which support a diverse range of specialized functionality. Pharm. Pathol. 82, 335340. Trends Biotechnol. Invest. Biochim. This canonical computational structure was determined to be highly similar to the envelope found via SAXS/SANS, where both consist of an extended molecular body accompanied by a protruding foot (Baldock et al., 2011). doi: 10.1016/j.cis.2010.10.003, Yeo, G. C., Tarakanova, A., Baldock, C., Wise, S. G., Buehler, M. J., and Weiss, A. S. (2016). Tropoelastin spherules assemble at the cell surface before deposition onto the microfibrillar scaffold in cell culture systems at physiological temperature (Kozel et al., 2006). The authors wrote and submitted this manuscript in response to an invitation by the Editor. Bochicchio, B., Yeo, G. C., Lee, P., Emul, D., Pepe, A., Laezza, A., et al. (2019). Approximately 90% of tropoelastins lysines undergo modification and/or participate in cross-links, indicating that mature elastin is extensively cross-linked (Kozel et al., 2003; Schmelzer et al., 2019). Coarse-grained model of tropoelastin self-assembly into nascent fibrils. For example, their inclusion in peptides derived from hydrophobic domains confers decreased times taken for self-assembly, most likely due to their favorable interaction with aqueous solvent (Miao et al., 2003). 278, 4855348562. 589(19 Pt A), 24772486. FEBS J. Allergan plc (NYSE: AGN), headquartered in Dublin, Ireland, is a bold, global biopharmaceutical company. Thus, elastin is responsible, in great part, for the properties of elastic fibers.

The advantage of coarse-grained methodologies is that they allow for the simulation of timescales of large molecular systems on the order of microseconds, which are otherwise computationally infeasible with classical full-atomistic molecular dynamics. doi: 10.1074/jbc.M212715200, Kumashiro, K.

The reduction in solvent accessible surface area of the mutant molecules suggests that the underlying mechanism for their altered self-assembly properties observed in experiments is due to less exposure of the appropriate hydrophobic domains required for coacervation. Tropoelastin is a unique protein with biochemical and physical properties that allow it to rapidly self-assemble into fibrous structures. Tropoelastin, the raw material used to create 'MeTro' elastic surgical glue developed with the University of Sydney, has been found to encourage stem cell growth - with the potential to ultimately help the body repair itself. Tropoelastin undergoes minimal energy loss during extension, similar to other polymers such as rubber and resilin (Elvin et al., 2005; Cordier et al., 2008; Baldock et al., 2011).

By probing mutations in computational studies that resolve the atomistic structure of the molecule, the deduction of mechanisms associated with changes to functional roles of specific domains has become feasible, and a connection between local structures and biological performance can be established (Figure 2; Tarakanova et al., 2018).

Combinations of these two amino acids result in domains that undergo rapid conformational sampling (Rauscher and Pomes, 2017), which, if perturbed toward a conformation that gravitate toward stability, will assemble into highly ordered amyloid-like fibrils that are not elastomeric (Rauscher et al., 2006; Roberts et al., 2015).

This model revealed that tropoelastin maintains a canonical or average structure based on the distribution of its possible conformations in spite of its flexible nature (Figure 2), as well as the possible roles that local structures play in biological processes, specifically, elastogenesis (Tarakanova et al., 2019b). eLife 6:e26526. doi: 10.1038/246461a0, Haust, M. D., More, R. H., Bencosme, S. A., and Balis, J. U. Additionally, elastin is remarkably durable as it is primarily deposited during prenatal development and childhood, and is rarely synthesized during adulthood. 3, 4 Elastin has a very low rate of turnover, so it .
