Location of a gelatin-binding region of human plasma fibronectin.
Plasma fibronectin, which is also known as cold-insoluble globulin, consists of two polypeptide chains of approximately 250,000 daltons joined by disulfide bonds located near one end of the molecule. Proteolytic digestion of human plasma fibronectin and NHz-terminal sequence analysis of some of the fragments produced were used to locate the gelatin-binding region of fibronectin within the intac...
متن کاملInteraction of gelatin with a fluorescein-labeled 42-kDa chymotryptic fragment of fibronectin.
A 42-kDa gelatin binding fragment of human plasma fibronectin was labeled with fluorescein and its fluid-phase interaction with gelatin was investigated. At 25 degrees C in 0.1 M Tris, 0.15 M NaCl, pH 7.3, a dissociation constant, Kd = 0.6 microM, was obtained from the dependence of fluorescence polarization on gelatin concentration. An identical value was obtained for the unlabeled fragment by...
متن کاملA 70-kDa amino-terminal fibronectin fragment supports gelatin binding to macrophages and decreases gelatinase activity.
We previously reported that a macrophage response that increased binding to 125I-radiolabeled soluble denatured collagen (gelatin) was induced by preincubation of macrophage with a 70-kDa amino-terminal fibronectin fragment and soluble nonlabeled gelatin [S. F. Penc, F. A. Blumenstock, J. E. Kaplan (1995) J. Leukoc. Biol. 58, 501-509]. We now report that neither protein synthesis nor recycling ...
متن کاملSelective binding affinity of human plasma fibronectin for the collagens I-IV.
The binding of plasma fibronectin to the collagens I, II, and III was greater in a cohort of glaucoma patients. In contrast, binding of plasma fibronectin to collagen type IV was less in 39 glaucoma patients than in any of 3 other diagnostic categories, including 92 patients that were normal, cataract, and glaucoma suspect patients. This observation may have significance in further understandin...
متن کاملDetermination of Superficial Clefts on Fragment of Antigen Binding in Human Immunoglobulin G by Computational Immunology
Background: Immunoglobulins (Igs) are protective glycoproteins specifically identify and eradicate microbes. Fragment of antigen binding (Fab) is a portion of antibody which binds to antigen and consists of one variable and one constant domain of one heavy and one light chain. Idiotypes, epitopes situated on Igs variable region, could be exploited to monitor and target malignant B cells and are...
