Beschreibung

General description

343.7/321.4/113.2/278.2/134.7 kDa (isoform 1/2/3/4/5 pro-form) and 340.8/318.5/110.4/275.3/131.8 kDa (isoform 1/2/3/4/5 mature form) calculated

Collagen alpha-3(VI) chain (UniProt P12111; also known as Collagen VI alpha-3 polypeptide) is encoded by the COL6A3 gene (Gene ID 1293) in human. Type VI collagen is an extracellular matrix (ECM) component present in virtually all connective tissues, including cartilage, bone, tendon, muscles and cornea, where it forms microfibrils in close association with basement membranes. In addition to anchoring the basement membrane to the pericellular matrix in muscle, research also indicates a role for collagen VI in cell signaling and cell migration. The basic structural unit of collagen VI is a heterotrimer composed of the alpha-1(VI), alpha-2(VI), and alpha-3(VI) chains (encoded by the COL6A1, COL6A2, and COL6A3 genes, respectively). The α1(VI) and α2(VI) chains are similar in size and domain structure, they contain a 335- or 336-amino acid triple helix region that is characteristic of all collagens. Flanking the triple helix are domains homologous to the A-type domains found in von Willebrand factor (VWA domains). α1(VI) and α2(VI) contain one VWA domain N-terminal to the triple helix (N1) and two VWA domains C-terminal of the helix (C1 and C2). The α3(VI) chain, on the other hand, is much larger with 10 N-terminal (N1–N10) and two C-terminal VWA domains (C1 and C2), and several other types of identifiable domains in the C terminal region (C3–C5). Mutations in the COL6A1, COL6A2, and COL6A3 genes are known causes of Ullrich congenital muscular dystrophy (UCMD) and Bethlem myopathy (BM). Three additional type VI collagen chains have been reported in 2008 (α4(VI), α5(VI) and α6(VI) chains encoded by COL6A4, COL6A5, and COL6A6, respectively).

Application

Flow Cytometry Analysis: A representative lot detected intracellular type VI collagen retention by flow cytometry using permeabilized and non-permeabilized fibroblasts isolated from both healthy individuals, as well as Ullrich congenital muscular dystrophy (UCMD) and Bethlem myopathy (BM) patients (Kim, J., et al. (2012). Neuromuscul. Disord. 22(2):139-148).
Immunocytochemistry Analysis: Representative lots detected extracellular type VI collagen immunoreactivity in cultured fibroblasts isolated from Ullrich congenital muscular dystrophy (UCMD) and Bethlem myopathy (BM) patients by fluorescent immunocytochemistry (Kim, J., et al. (2012). Neuromuscul. Disord. 22(2):139-148; Allamand, V., et al. (2011). Skelet Muscle. 1:30; Briñas, L., et al. (2010). Ann. Neurol. 68(4):511-520; Jimenez-Mallebrera, C., et al. (2006).

Immunocytochemistry Analysis: A representative lot detected exogenously expressed wild-type α3(VI) chain, as well as α3(VI) chain with G49A or G301V mutation in SaOS-2 transfectants by fluorescent immunocytochemistry (Lamandé, S.R., et al. (2002). J. Biol. Chem. 277(3):1949-1956).
Immunocytochemistry Analysis: Representative lots immunostained extracellular type VI collagen fibrils in human MG63 osteosarcoma cells and primary foreskin fibroblasts cultures (Bruns, R.R., et al. (1986). J. Cell Biol. 103(2):393-404; Engvall, E., et al. (1986). J. Cell Biol. 102(3):703-710).
Immunohistochemistry Analysis: A representative lot detected human type VI collagen immunoreactivity in frozen muscle tissue sections from mice grafted with human synovial stem cells (hSSCs) by fluorescent immunohistochemistry (Meng, J., et al. (2010). Neuromuscul. Disord. 20(1):6-15).
Immunohistochemistry Analysis: Representative lots detected type VI collagen immunoreactivity in muscle and skin samples from congenital muscular dystrophy (CMD) and Ullrich congenital muscular dystrophy (UCMD) patients by fluorescent immunohistochemistry using frozen tissue sections (Peat, R.A., et al. (2008). Neurology. 71(5):312-321; Jimenez-Mallebrera, C., et al. (2006). Neuromuscul. Disord. 16(9-10):571-582).
Immunoprecipitation Analysis: A representative lot co-immunoprecipitated type VI collagen α1(VI) and α2(VI) chains with wild-type α3(VI) chain, as well as α3(VI) chain with G16S or G49A mutation. Impaired α1(VI) and α2(VI) co-IP was observed with α3(VI) G301V mutant (Lamandé, S.R., et al. (2002). J. Biol. Chem. 277(3):1949-1956).
Immunoprecipitation Analysis: A representative lot immunoprecipitated type VI collagen alpha chains from Triton X-100 extracts of MRC-5 human lung fibroblasts (Engvall, E., et al. (1986). J. Cell Biol. 102(3):703-710).
Electron Microscopy Analysis: A representative lot detected reduced extracellular type VI collagen immunoreactivity in cultured fibroblasts isolated from an Ullrich congenital muscular dystrophy (UCMD) patient (Zhang, R.Z., et al. (2002). J. Biol. Chem. 277(46):43557-43564).
Electron Microscopy Analysis: A representative lot immunostained extracellular filaments and fibrils by binding to the band (non-helical) region of the type VI collagen fibrils using cultured human foreskin fibroblasts (Bruns, R.R., et al. (1986). J. Cell Biol. 103(2):393-404).
Dot Blot Analysis: A representative lot detected exogenously expressed wild-type α3(VI) chain, as well as α3(VI) chain with G49A or G301V mutation in the medium of cultured SaOS-2 transfectants (Lamandé, S.R., et al. (2002). J. Biol. Chem. 277(3):1949-1956).
