Tropoelastin is a protein, of size 72kDa, that comes together via cross-links to form elastin in the extracellular matrix of the cell. (wikipedia.org)
We are interested how extracellular matrix proteins instruct cells to differentiate, migrate, and proliferate, and how cells sense normal and pathologically altered extracellular matrix. (mcgill.ca)
The extracellular matrix contains fibres made out of protein. (leeds.ac.uk)
Tropoelastin is secreted from the cell, and elastin fibres are assembled close to the extracellular surface of the cell, onto a scaffold of microfibrils. (leeds.ac.uk)

Lastly, we revealed that addition of type IV collagen protein induced myofibroblast proliferation and migration in monolayer culture and increased the formation of mesenchymal-epithelial septal-like structures in co-culture. (biomedcentral.com)
d - i Type IV collagen protein and mRNA expression in the lung. (biomedcentral.com)
It is secreted by fibroblasts as procollagen , and amino acid residues at the ends of the protein are cleaved off outside the cell to form collagen, which then aggregates into fibres, etc. (leeds.ac.uk)
Collagen consists of three protein chains which wrap around each other in a helical arrangement. (leeds.ac.uk)

In general, these polymers are linear below the Tt, but aggregate into spherical clumps above the Tt. (wikipedia.org)

The ability of ELPs to undergo morphological changes at certain temperatures enables specific proteins that are bound to the ELPs to be separated out from the rest of the solution via experimental techniques such as centrifugation. (wikipedia.org)
Elastin-like polypeptides (ELP) undergo temperature-dependent inverse phase transition and ELPylated proteins can be purified simply by inverse transition cycling (ITC). (biomedcentral.com)

It is at this temperature that the ELPs move from a linear, relatively disordered state to a more densely aggregated, partially ordered state Although given as a single temperature, Tt, the ELP phase change process generally begins and ends within a temperature range of approximately 2 °C. Also, Tt is altered by the addition of unique proteins to the free ELPs. (wikipedia.org)

The research themes rank around molecular mechanisms matrix proteins and fibers exert in disorders affecting blood vessels, bone, skin and adipose tissue. (mcgill.ca)
Due to their large surface area and ability to interact with proteins and peptides, graphene oxides offer valuable physiochemical and biological features for biomedical applications and have been successfully employed for optimizing scaffold architectures for a wide range of organs, from the skin to cardiac tissue. (mdpi.com)

Thus, ELPs consisting of the Val-Pro-Gly-X-Gly monomeric units, which bear resemblance to the repetitive tropoelastin hydrophobic domains, are highly disordered below their Tt. (wikipedia.org)
Assembly of polymeric elastin into its final architecture in the extracellular matrix involves both self-aggregation properties of its monomeric precursor, tropoelastin, and interactions with several matrix-associated proteins that appear to act by modulating the intrinsic self-assembly of tropoelastin. (nih.gov)

Elastin is a protein that provides the unusual properties of extensibility and elastic recoil to tissues. (nih.gov)

Because of its highly nonpolar character and propensity to self-aggregate, it has been suggested that mechanisms limiting self-aggregation must also be present during the transit of tropoelastin through the cell prior to secretion. (nih.gov)
This review explores the potential pathogenic mechanisms of cerebral vasospasm and the impacts of ECM protein metabolism on the vascular wall during ECM remodelling. (biomedcentral.com)

They account for the majority of proteins in the ECM , which makes them the most abundant proteins in the human body. (amboss.com)

The TGF-beta family of proteins, namely TGF-beta1, TGF-beta2 and TGF-beta3 with their specific cell surface receptors TGF RI, TGF RII, TGF RIII are known to act on several crucial aspects of embryonal and mainly mesenchymal/neuroektodermal organ development. (justia.com)

One of the major reasons that elastin can withstand high levels of stress in the body without experiencing any physical deformation is that the underlying tropoelastin contains domains that are highly hydrophobic. (wikipedia.org)

Both proteins also modify the kinetics of self-assembly of tropoelastin in an in vitro system, consistent with a role in attenuating the premature intracellular self-aggregation of tropoelastin through a mechanism that limits the growth and maturation of aggregates. (nih.gov)
