  • Target

    • FunctionType IV collagen is the major structural component of glomerular basement membranes (GBM), forming a 'chicken-wire' meshwork together with laminins, proteoglycans and entactin/nidogen.
      Arresten, comprising the C-terminal NC1 domain, inhibits angiogenesis and tumor formation. The C-terminal half is found to possess the anti-angiogenic activity. Specifically inhibits endothelial cell proliferation, migration and tube formation. Inhibits expression of hypoxia-inducible factor 1alpha and ERK1/2 and p38 MAPK activation. Ligand for alpha1/beta1 integrin.
    • Tissue specificityHighly expressed in placenta.
    • Involvement in diseaseDefects in COL4A1 are a cause of brain small vessel disease with hemorrhage (BSVDH) [MIM:607595]. Brain small vessel diseases underlie 20 to 30 percent of ischemic strokes and a larger proportion of intracerebral hemorrhages. Inheritance is autosomal dominant.
      Defects in COL4A1 are the cause of hereditary angiopathy with nephropathy aneurysms and muscle cramps (HANAC) [MIM:611773]. The clinical renal manifestations include hematuria and bilateral large cysts. Histologic analysis revealed complex basement membrane defects in kidney and skin. The systemic angiopathy appears to affect both small vessels and large arteries.
      Defects in COL4A1 are a cause of porencephaly familial (PCEPH) [MIM:175780]. Porencephaly is a term used for any cavitation or cerebrospinal fluid-filled cyst in the brain. Porencephaly type 1 is usually unilateral and results from focal destructive lesions such as fetal vascular occlusion or birth trauma. Type 2, or schizencephalic porencephaly, is usually symmetric and represents a primary defect or arrest in the development of the cerebral ventricles.
    • Sequence similaritiesBelongs to the type IV collagen family.
      Contains 1 collagen IV NC1 (C-terminal non-collagenous) domain.
    • DomainAlpha chains of type IV collagen have a non-collagenous domain (NC1) at their C-terminus, frequent interruptions of the G-X-Y repeats in the long central triple-helical domain (which may cause flexibility in the triple helix), and a short N-terminal triple-helical 7S domain.
    • Post-translational
      Lysines at the third position of the tripeptide repeating unit (G-X-Y) are hydroxylated in all cases and bind carbohydrates.
      Prolines at the third position of the tripeptide repeating unit (G-X-Y) are hydroxylated in some or all of the chains.
      Type IV collagens contain numerous cysteine residues which are involved in inter- and intramolecular disulfide bonding. 12 of these, located in the NC1 domain, are conserved in all known type IV collagens.
      The trimeric structure of the NC1 domains is stabilized by covalent bonds between Lys and Met residues.
      Proteolytic processing produces the C-terminal NC1 peptide, arresten.

    • ab19808 staining Collagen IV in mouse tooth tissue section by Immunohistochemistry (Frozen sections). Tissue samples were blocked with 1% BSA for 20 minutes at 200C and incubated with undiluted primary antibody for 1 hour at 200C. An Alexa Fluor®594-conjugated chicken polyclonal to rabbit IgG was used as secondary antibody at 1/500 dilution. Red colour in the image represents staining of CoIlagen-IV and the green is for CD31, yellow for ED16+6, which were purchased from different sources.

    • ab19808 staining Collagen IV in murine brain tissue/ human xenograft tissue by Immunohistochemistry.
      Tissue was fixed in AFA (alcohol-formal-acetate) and a heat mediated antigen retrieval step was performed using Tris-EDTA pH 9. Samples were then blocked using 3% BSA for 30 minutes at 20°C and then incubated with ab19808 at a 1/500 dilution for 1 hour and 30 minutes. The secondary used was an undiluted HRP-conjugated goat polyclonal.

    • ab19808 staining Collagen IV in mouse brain cells (ab30149) by ICC/IF (Immunocytochemistry/immunoflurescence). Cells were fixed with formaldehyde and blocked with 0.25% TNB for 30 minutes at 22°C. Samples were incubated with primary antibody 1/250 in TNB for 18 hours at 22°C. A Biotin-conjugated Goat polyclonal to rabbit IgG (ab6720), dilution 1/500, was used as secondary antibody.
