Even though there is clear evidence that these cartilage matrix proteins interact with each other, their exact functions in matrix organisation and bone development still need to be elucidated.
These adhesion proteins are needed for leukocytes to move from the blood into peripheral tissues [ 20, 24] and they mediate leukocyte interactions with endothelial cells and extracellular matrix proteins (ECM) [ 20].
Sun, Y., Jallerat, Q., Szymanski, J. M. & Feinberg, A. W. Conformal nanopatterning of extracellular matrix proteins onto topographically complex surfaces.
Among the matrix proteins with CTDC domains, four (pdiA, psiA, psiF and psiN) also act as signals or signal regulators.
Myofibroblasts are known to produce ECM matrix proteins for the remodeling of the stromal tissue during corneal wound healing1.
Vaquero, E. C. et al. Extracellular matrix proteins protect pancreatic cancer cells from death via mitochondrial and nonmitochondrial pathways.
The mitochondrial protein import machinery is complex because a heterogeneous set of proteins needs to be correctly targeted to several different compartments within the mitochondrion: the matrix, the outer membrane (OM), the inner membrane (IM) and the intermembrane space (IMS).
On the other hand, expression of extracellular matrix proteins is a marker of inflammation, too, as immune cells need to attach to matrix proteins whilst moving themselves to the site of infection in the lung.
They may also be useful in tissue engineering by removal of the need for biologically-derived components such as extracellular matrix proteins.
Mutants lacking various matrix molecules or enzymes needed for matrix protein production display thin myocardial walls that lack trabeculae in addition to ECC defects (Camenisch et al., 2002; Camenisch et al., 2000; Mjaatvedt et al., 1998; Yamamura et al., 1997), highlighting the similar processes needed to create these disparate structures.
