Fibronectin: Molecular Structure, Fibrillar Structure and ...
Keywords: fibronectin, fibrillogenesis, extracellular matrix, biomechanics, mechanobiology. 1. Introduction. The extracellular matrix (ECM) is a substrate for cells that modulates migration, proliferation, differentiation, spreading and survival by serving as both a molecular reservoir and a structural scaffold with tissue-specific mechanical ...
Fibronectin - Wikipedia
Fibronectin exists as a protein dimer, consisting of two nearly identical monomers linked by a pair of disulfide bonds. [6] The fibronectin protein is produced from a single gene, but alternative splicing of its pre-mRNA leads to the creation of several isoforms. Two types of fibronectin are present in vertebrates: [6]

2021年9月16日 · In times of ECM assembly and turnover, cells upregulate assembly of the ECM protein, fibronectin (FN). FN is assembled by cells into viscoelastic fibrils that can bind upward of 40 distinct...
Fibronectin - an overview | ScienceDirect Topics
Fibronectin is an extracellular glycoprotein that binds integrins on cell membranes to external molecules like collagen and glycosaminoglycans. It is used in biomaterials to enhance cell-biomaterial adhesion and has been shown to promote axonal regeneration and myelination in spinal cord injury models.
Fibronectin - an overview | ScienceDirect Topics
Fibronectin is a high-molecular weight glycoprotein of the extracellular matrix and binds cells through membrane-spanning receptor proteins called integrins [72]. It was observed that in response to injury, secretion of fibronectin from cardiac valve interstitial cells occurred and formed fibrillar adhesions [73]. Fibronectin is mainly involved ...

The extracellular matrix (ECM) plays a key role as both structural scaffold and regulator of cell signal transduction in tissues. In times of ECM assembly and turnover, cells upregulate assembly of the ECM protein, fibronectin (FN). FN is assembled by cells into viscoelastic fibrils that can bind upward of 40 distinct growth factors and cytokines.
Fibronectin: a brief overview of its structure, function, and ...
Fibronectin is a large glycoprotein that is composed of blocks of three types of repeating, homologous peptide sequences. Several of the homologous blocks form functional domains that are organized in a linear array on two nearly identical subunit arms. Specific domains allow fibronectin to promote …

2023年6月13日 · Fibronectin and laminin are significantly smaller than either collagens or proteoglycans, and play different roles in the extracellular matrix. Fibronectin is formed by the joining of two similar polypeptide subunits via a pair of disulfide bonds near the C-terminal of each (Figure \(\PageIndex{5}\)).

2006年10月10日 · Fibronectin is recognized by integrins alpha5beta1 and alphaVbeta3. The primary sequence motif of fibronectin for integrin binding is a tripeptide, Arg-Gly-Asp (RGD), located on the loop connecting the force-bearing G- and F-strands of FN-III10.
