Vascular anticoagulant alpha (VAC alpha, annexin V) is a member of the family of calcium and phospholipid binding proteins, the annexins. The binding properties of VAC alpha to phospholipid bilayers were studied by ellipsometry. Adsorption was calcium-dependent and completely reversible upon calcium depletion. Half-maximal adsorptions to phospholipid(More)
Plectin, the most versatile cytolinker identified to date, has essential functions in maintaining the mechanical integrity of skin, skeletal muscle and heart, as indicated by analyses of plectin-deficient mice and humans. Expression of plectin in a vast variety of tissues and cell types, combined with a large number of different binding partners identified(More)
We have determined the complete cDNA sequence of rat plectin from a number of well-characterized overlapping lambda gt11 clones. The 4,140-residue predicted amino acid sequence (466,481 D) is consistent with a three-domain structural model in which a long central rod domain, having mainly an alpha-helical coiled coil conformation, is flanked by globular(More)
Plectin, a 500-kDa intermediate filament binding protein, has been proposed to provide mechanical strength to cells and tissues by acting as a cross-linking element of the cytoskeleton. To set the basis for future studies on gene regulation, tissue-specific expression, and pathological conditions involving this protein, we have cloned the human plectin(More)
Plectin is a widely expressed protein that is very large in size and that has all the attributes of a multifunctional crosslinking and organizing element of the cytoskeleton. It displays a multidomain structure, versatile binding activities, and subcellular localizations that enable it to strengthen cells against mechanical stress forces. Moreover,(More)
We report the identification of a novel human tumor associated gene, CDCP1 (Cub Domain Containing Protein), which was identified using representational difference analysis and cDNA chip technology. The gene consists of eight exons, the upstream region of which neither contains a TATA- nor a CCAAT-box. However, a CpG island is located around the(More)
Tumor necrosis factor-alpha (TNF-alpha), a protein released by activated macrophages, is involved in a wide variety of human diseases including septic shock, cachexia, and chronic inflammation. TNF binding protein (TNF-BP), a glycoprotein with high affinity to TNF-alpha isolated from urine, acts as an inhibitor of TNF-alpha by competing with the(More)
Based on sequence information from tryptic peptides an almost full-size cDNA coding for the human vascular anticoagulant was isolated from a placental cDNA library and sequenced. The coding region was cloned into an Escherichia coli expression vector and the protein expressed at high levels. The recombinant protein was purified and found to be(More)
A cDNA was cloned coding for a new member of the human Ca2+-modulated phospholipid-binding protein family termed annexins. Due to its 56% identity to the human vascular anticoagulant (VAC) the new protein is named VAC-beta, renaming the previous VAC as VAC-alpha. Northern analysis detects one hybridizing mRNA species of 2.2 kb in human placenta. Genomic(More)
Annexin VIII is a calcium-dependent phospholipid-binding protein previously identified as a blood anticoagulant based on in vitro studies. However, the physiologic function of annexin VIII remains unknown. In acute promyelocytic leukemia (APL) the annexin VIII gene is highly expressed, but its expression is undetectable in the blasts of other acute(More)
