Structure of the human type IV collagen gene COL4A3 and mutations in autosomal Alport syndrome.
Mutations in either the COL4A3 or the COL4A4 genes, encoding the alpha3 and alpha4 chains of type IV collagen, are responsible for the autosomal-recessive form of Alport syndrome, a progressive hematuric nephropathy characterized by glomerular basement membrane abnormalities. Reported here are the complete COL4A3 exon-intron structure and a comprehensive screen for mutations of the 52 COL4A3 ex...
متن کاملStructure of the human type IV collagenase gene.
The structure of the gene for human 70-kDa type IV collagenase (gelatinase) was determined. Three overlapping genomic clones were isolated and shown to contain 0.4 kilobase (kb) of the 5'-flanking region, the 27-kb structural gene, and 4.5 kb of the 3'-flanking region. The gene has 13 exons that vary in length from 110 to 901 base pairs (bp) and 12 introns that range from 175 to 4350 bp. Alignm...
متن کاملStudy of Basement Membrane Type IV Collagen Appearance in the Brain Choroids Plexus of Mouse Fetuses
Introduction & Objective: The brain choroids plexus (BCP) plays an important role in the cerebrospinal fluid (CSF) production, but its characterization is still incomplete. Collagen type IV, is one of the most important proteins of basement membrane (BM) and extracellular matrix (ECM) of BCP. In the present study we investigated the differential period of type IV collagen in basement membrane...
متن کاملStructural studies on human type IV collagen.
Type IV collagen was isolated from limited pepsin digests of human placenta by selective salt precipitation at acidic and neutral pH. The native protein was resistant to human skin collagenase but was cleaved by a rat mast cell protease. Molecular sieve chromatography of the reduced and alkylated material separated relatively homogeneous components of molecular weight 140,000 (140K) and 100,000...
متن کاملThe Role of Type IV Collagen in Developing Lens in Mouse Fetuses
Objective(s) Extracellular matrix (ECM) and basement membrane (BM) play important roles in many developmental processes during development and after birth. Among the components of the BM, collagen fibers specially type IV are the most important parts. The aim of this study was to determine the time when collagen type IV appears in the BM of lens structure during mouse embryonic development. M...
