Lack of cytosolic and transmembrane domains of type XIII collagen results in progressive myopathy. (1/11)Type XIII collagen is a type II transmembrane protein found at many sites of cell adhesion in tissues. Homologous recombination was used to generate a transgenic mouse line (Col13a1(N/N)) that expresses N-terminally altered type XIII collagen molecules lacking the short cytosolic and transmembrane domains but retaining the large collagenous ectodomain. The mutant molecules were correctly transported to focal adhesions in cultured fibroblasts derived from the Col13a1(N/N) mice, but the cells showed decreased adhesion when plated on type IV collagen. These mice were viable and fertile, and in immunofluorescence stainings the mutant protein was located in adhesive tissue structures in the same manner as normal alpha1(XIII) chains. In immunoelectron microscopy of wild-type mice type XIII collagen was detected at the plasma membrane of skeletal muscle cells whereas in the mutant mice the protein was located in the adjacent extracellular matrix. Affected skeletal muscles showed abnormal myofibers with a fuzzy plasma membrane-basement membrane interphase along the muscle fiber and at the myotendinous junctions, disorganized myofilaments, and streaming of z-disks. The findings were progressive and the phenotype was aggravated by exercise. Thus type XIII collagen seems to participate in the linkage between muscle fiber and basement membrane, a function impaired by lack of the cytosolic and transmembrane domains. (+info)
The type XIII collagen ectodomain is a 150-nm rod and capable of binding to fibronectin, nidogen-2, perlecan, and heparin. (2/11)Type XIII collagen consists of a short N-terminal intracellular domain, a transmembrane domain, and a collagenous ectodomain, and it is found at many sites of cell adhesion. We report on the characterization of recombinant type XIII collagen. The shed ectodomain was purified from insect cell culture medium and shown to form 240-kDa trimers with a T(m) of 42 degrees C. Correct chain association into a triple-helical conformation was confirmed by limited pepsin digestion and CD spectroscopy. Rotary shadowing electron microscopy of the ectodomain revealed it to be a 150-nm rod with two flexible hinges separating 31-, 52-, and 68-nm portions. The rods represent the collagenous domains 1-3, and the hinges coincide with the non-collagenous domains 2 and 3. By using surface plasmon resonance analysis, the ectodomain showed interaction with immobilized fibronectin, nidogen-2, and perlecan with K(D) values in the nanomolar range. The binding sites of type XIII collagen for fibronectin were localized to the collagenous domains, whereas the binding activities for nidogen-2 and perlecan resided in the pepsin-sensitive portions of the ectodomain. Furthermore, the ectodomain bound significantly to heparin, which also inhibited shedding of the ectodomain in insect cell cultures. The results reveal that type XIII collagen is notably distinct in its structure compared with other cell-surface proteins, and the in vitro binding with fibronectin, heparin, and two basement membrane components is indicative of multiple cell-matrix interactions in which this ubiquitously expressed protein participates.

Type XIII collagen and some other transmembrane collagens contain two separate coiled-coil motifs, which may function as independent oligomerization domains. (3/11)Type XIII collagen is a homotrimeric transmembrane collagen composed of a short intracellular domain, a single membrane-spanning region, and an extracellular ectodomain with three collagenous domains (COL1-3) separated by short non-collagenous domains (NC1-4). Several collagenous transmembrane proteins have been found to harbor a conserved sequence next to their membrane-spanning regions, and in the case of type XIII collagen this sequence has been demonstrated to be important for chain association. We show here that this 21-residue sequence is necessary but not sufficient for NC1 association. Furthermore, the NC1 association region was predicted to form an alpha-helical coiled-coil structure, which may already begin at the membrane-spanning region, as is also predicted for the related collagen types XXIII and XXV. Interestingly, a second coiled-coil structure is predicted to be located in the NC3 domain of type XIII collagen and in the corresponding domains of types XXIII and XXV. It is found experimentally that the absence of the NC1 coiled-coil domain leads to a lack of disulfide-bonded trimers and misfolding of the membrane-proximal collagenous domain COL1, whereas the COL2 and COL3 domains are correctly folded. We suggest that the NC1 coiled-coil domain is important for association of the N-terminal part of the type XIII collagen alpha chains, whereas the NC3 coiled-coil domain is implicated in the association of the C-terminal part of the molecule. All in all, we propose that two widely separated coiled-coil domains of type XIII and related collagens function as independent oligomerization domains participating in the folding of distinct areas of the molecule.

The shed ectodomain of type XIII collagen affects cell behaviour in a matrix-dependent manner. (4/11)Transmembrane type XIII collagen resides in adhesive structures of cells and tissues, and has therefore been implicated in cell adhesion and in adhesion-dependent cell functions. This collagen also exists as a soluble protein in the pericellular matrix, as the ectodomain is released from the plasma membrane by proteolytic cleavage. Analysis with various protease inhibitors led to confirmation of the furin family of proprotein convertases as the protease group responsible for the shedding of the ectodomain, cleaving at a site conforming to the consensus sequence for the proprotein convertases at the stem of the ectodomain. Both the trans -Golgi network and the plasma membrane were used as cleavage locations. Mammalian cells employed various intracellular mechanisms to modulate shedding of the ectodomain, all resulting in a similar cleavage event. Cell detachment from the underlying substratum was also found to augment the excision. The released ectodomain rendered the pericellular surroundings less supportive of cell adhesion, migration and proliferation, as seen specifically on a vitronectin substratum. Type XIII collagen ectodomain shedding thus resulted in the formation of a soluble, biologically active molecule, which eventually modulated cell behaviour in a reciprocal and substratum-specific manner. The dual existence of membrane-bound and soluble variants widens our biological understanding of type XIII collagen. (+info)
The shed ectodomain of type XIII collagen associates with the fibrillar fibronectin matrix and may interfere with its assembly in vitro. (5/11)Type XIII collagen is a transmembrane collagen, which is known to exist also as a soluble variant due to ectodomain shedding. Earlier studies with the recombinant ectodomain have shown it to interact in vitro with a number of extracellular matrix proteins, e.g. Fn (fibronectin). In view of its strong binding to Fn, we examined in the present study whether the released soluble ectodomain can bind to the fibrillar Fn matrix under cell-culture conditions and, if so, influence its assembly. In this study, we demonstrate that the type XIII collagen ectodomain of mammalian cells can associate with Fn fibres and may eventually hamper incorporation of the fibrillar Fn meshwork. The association between type XIII collagen and Fn was implicated to be mediated by the C-terminal end of type XIII collagen and the N-terminal end of Fn. The results presented here imply that the shedding of the type XIII collagen ectodomain results in a biologically active molecule capable of remodelling the structure of the pericellular matrix. (+info)
Modulation of the cellular cholesterol level affects shedding of the type XIII collagen ectodomain. (6/11)Type XIII collagen is a transmembrane protein that also exists as a soluble extracellular variant because of ectodomain shedding by proprotein convertases. Because ectodomain shedding in a growing number of transmembrane proteins has recently been shown to be dependent on their localization in cholesterol-enriched detergent-resistant membrane microdomains, this work aimed at analyzing this aspect of type XIII collagen ectodomain processing. In HT-1080 cells type XIII collagen and its cleaving proprotein convertase furin localized partially in detergent-resistant cholesterol-containing membrane microdomains. Disruption of these domains by lowering either the level or availability of the cellular cholesterol reduced ectodomain shedding, implying that, in such membrane domains correct cholesterol level is important for the regulation of type XIII collagen ectodomain processing. In addition, we show here that ectodomain of type XIII collagen is also shed intracellularly. HT-1080 cells released vesicles from the Golgi apparatus, which contained only the cleaved variant. Intracellular processing and the subsequent entry of the cleaved ectodomain into the vesicles was totally blocked by inhibition of the proprotein convertase function by cell-permeable chloromethylketone, but not with cell-impermeable alpha1-antitrypsin Portland. This supports the hypothesis of type XIII collagen ectodomain also being cleaved intracellularly in the Golgi and suggests that the intracellular cleavage may act as a gating event in the vesicle-mediated ectodomain secretion.

Cleavage and oligomerization of gliomedin, a transmembrane collagen required for node of ranvier formation. (7/11)Gliomedin, which has been implicated as a major player in genesis of the nodes of Ranvier, contains two collagenous domains and an olfactomedin-like domain and belongs to the group of type II transmembrane collagens that includes collagens XIII and XVII and ectodysplasin A. One characteristic of this protein family is that constituent proteins can exist in both transmembrane and soluble forms. Recently, gliomedin expressed at the tips of Schwann cell microvilli was found to bind axonal adhesion molecules neurofascin and NrCAM in interactions essential for Na(+)-channel clustering at the nodes of Ranvier in myelinating peripheral nerves. Interestingly, exogenously added olfactomedin domain was found to have the same effect as intact gliomedin. Here we analyze the tissue form of gliomedin and demonstrate that the molecule not only exists as full-length gliomedin but also as a soluble form shed from the cell surface in a furin-dependent manner. In addition, gliomedin can be further proteolytically processed by bone morphogenetic protein 1/Tolloid-like enzymes, resulting in release of the olfactomedin domain from the collagen domains. Interestingly, the later cleavage induces formation of higher order, insoluble molecular aggregates that may play important roles in Na(+)-channel clustering. (+info)
The role of disulfide bonds and alpha-helical coiled-coils in the biosynthesis of type XIII collagen and other collagenous transmembrane proteins. (8/11)Type XIII collagen is a type II transmembrane protein with three collagenous (COL1-3) and four noncollagenous domains (NC1-4). The human alpha1(XIII) chain contains altogether eight cysteine residues. We introduced point mutations to six of the most N-terminal cysteine residues, and we show here that the two cysteines 117 and 119 at the end of the N-terminal noncollagenous domain (NC1) are responsible for linking the three alpha1(XIII) chains together by means of interchain disulfide bonds. In addition, the intracellular and transmembrane domains have an impact on trimer formation, whereas the cysteines in the transmembrane domain and the COL1, the NC2, and the C-terminal NC4 domains do not affect trimer formation. We also suggest that the first three noncollagenous domains (NC1-3) harbor repeating heptad sequences typical of alpha-helical coiled-coils, whereas the conserved NC4 lacks a coiled-coil probability. Prevention of the coiled-coil conformation in the NC3 domain is shown here to result in labile type XIII collagen molecules. Furthermore, a new subgroup of collagenous transmembrane proteins, the Rattus norvegicus, Drosophila melanogaster, and Caenorhabditis elegans colmedins, is enlarged to contain also Homo sapiens collomin, and Pan troglodytes, Mus musculus, Tetraodon nigroviridis, and Dano rerio proteins. We suggest that there is a structurally varied group of collagenous transmembrane proteins whose biosynthesis is characterized by a coiled-coil motif following the transmembrane domain, and that these trimerization domains appear to be associated with each of the collagenous domains. In the case of type XIII collagen, the trimeric molecule has disulfide bonds at the junction of the NC1 and COL1 domains, and the type XIII collagen-like molecules (collagen types XXIII and XXV) and the colmedins are similar in that they all have a pair of cysteines in the same location. Moreover, furin cleavage at the NC1 domain can be expected in most of the proteins. (+info)

Collagen α-1 (XXIII) chain is a protein encoded by COL23A1 gene, which is located on chromosome 5q35 in humans, and on chromosome 11B1+2 in mice. The location of this gene was discovered by genomic sequence analysis. Collagen XXIII is a type II transmembrane protein and the fourth in the subfamily of non-fibrillar transmembranous collagens. This kind of collagens have a single pass hydrophobic transmembrane domain. The molecule of collagen XXIII can be found either in membrane-bond form or in shed form. Type XXIII collagen is expressed in both adult tissues and developing organs. It can be found in the epidermis and other epithelia such as those in tongue, gut and lung, but also in the brain, the kidney and the cornea. It has been shown that in prostate collagen XXIII expression is associated with tumor progression. The functions of collagen XXIII are still unknown, although it is believed that they could be similar to other transmembrane proteins, such as collagen XIII. Collagen XXIII was ...

The cornea is a curved and transparent structure that provides the initial focusing of a light image into the eye. It consists of a central stroma that constitutes 90% of the corneal depth, covered anteriorly with epithelium and posteriorly with endothelium. Its transparency is the result of the regular spacing of collagen fibers with remarkably uniform diameter and interfibrillar space. Corneal collagen is composed of heterotypic fibrils consisting of type I and type V collagen molecules. The cornea also contains unusually high amounts of type VI collagen, which form microfibrillar structures, FACIT collagens (XII and XIV), and other nonfibrillar collagens (XIII and XVIII). FACIT collagens and other molecules, such as leucine-rich repeat proteoglycans, play important roles in modifying the structure and function of collagen fibrils.Proteoglycans are macromolecules composed of a protein core with covalently linked glycosaminoglycan side chains. Four leucine-rich repeat proteoglycans are present ...
Moreover, there are some collagen molecules containing sequences of hydrophobic amino acids inserted in the plasma membrane. For example, type XIII and XVII collagens. Collagen type XVII is part of the molecular structure of hemidesmosomes. No matter the type, collagen is synthesized inside the cell as a precursor: the pro-collagen molecule. First, alpha chains are synthesized in the endoplasmic reticulum, where proline becomes hydroxyproline by hydroxylation. Proline and hydroxyproline may be up to 20 % of the alpha chain. GLycosylation (type O-glycosylation) of alpha chains also occurs in the reticulum. At this point, three alpha chains join together by hydrogen bonds to finally form the pro-collagen molecule. Disulfide bridges are also formed between the alpha chains. Pro-collagen molecules are recognized and linked by transmembrane receptors and packaged in COPII coated vesicles. Typical COPII vesicles are 60 to 90 nm in diameter, but COPII vesicles transporting pro-collagen are 500 nm in ...

Martin Khor. On 21 April, the UNCTAD ministerial conference known as UNCTAD XIII begins in Doha. It is shaping up as an important milestone to reaffirm - or not - the mandate given to UNCTAD to work on key global economic issues, including finance and macro-economic policy.. In fact, UNCTAD enjoys that mandate already, given its role in the UN system to organize an integrated perspective on trade, finance and economic issues.. However, some developed countries have attempted to dilute the specific issues that the UNCTAD secretariat has highlighted in recent years, especially in the wake of the global financial and economic crisis.. A draft outcome document prepared in Geneva by delegates is being transferred for continued negotiation in Doha with the hope that a consensus can be reached by 26 April, when UNCTAD XIII ends.. A major contentious point is whether UNCTAD XIII reaffirms the Accra Accord, adopted at UNCTAD XII in Accra in 2008. The Accord gave UNCTAD a mandate to work on a broad range ...

The administration of F XIII in septic animals prevented the decrease of mucosal FCD as seen in the untreated LPS group compared to controls. We could not detect an influence of F XIII administration on leukocyte to endothelium interaction and plasma extravasation. After three hours, endotoxemia resulted in an expected decrease in F XIII activity compared to the control group. The decrease of F XIII in our sepsis model correlates with findings of clinical investigations in septic patients [18,19]. However, through F XIII substitution in the treatment group we achieved F XIII levels comparable to controls after three hours of endotoxemia.. In our study we found a higher FCD in the F XIII group compared to untreated endotoxemic animals, indicating that perfusion in capillaries of the intestinal mucosa was protected by F XIII administration. It appears that not only the preservation of microcirculation but also pro-angiogenic properties are related to the effects of factor XIII. In vitro F XIII ...

- Transcripts of MMP-1, -8, -13 and TIMP-1 were detected in all cell lines by RT-PCR and the corresponding proteins were found in the cytoplasm of all three cell lines by Western blot analysis and/or immunocytochemistry. (uni-bielefeld.de)
- Corneal wound healing is a complex process involving many cell types, signaling pathways, and proteins. (arvojournals.org)
- Transgenic rescue of DINE KO mice was accomplished by overexpression of wild-type DINE, but not by protease domain-mutated DINE. (jneurosci.org)
- Corneal scars from a 7-month-old mouse revealed an overexpression of type XII collagen in the wound area similar to what we observed in human corneal scars. (arvojournals.org)
- Alternative splice variants of the NC3 and NC1 domains of type XII collagen were investigated in the mouse wound-healing model using RT-PCR. (arvojournals.org)
- In a mouse model of corneal wound injury we found that at 14 and 21 days postexcision, type XII collagen was largely concentrated in the subepithelial region of the cornea, especially in and near the wound bed. (arvojournals.org)
- Type XII collagen is overexpressed in permanent human and mouse corneal scars and could represent a new target to treat corneal scarring. (arvojournals.org)
