Escherichia coli maltose binding protein (MBP) is commonly used to promote the solubility of its fusion partners. To investigate the mechanism of solubility enhancement by MBP, we compared the properties of MBP fusion proteins refolded in vitro with those of the corresponding fusion proteins purified under native conditions. We fused five aggregation-prone passenger proteins to 3 different N-te...
The human mannose-binding protein (MBP) is a multimeric serum protein that is divided into three domains, a cysteine-rich NH2-terminal domain that stabilizes the collagen alpha helix of the second domain and a third COOH-terminal carbohydrate recognition domain. Previous studies have shown that both native and recombinant human MBP bind to wild-type virulent Salmonella montevideo that expresses...
BACKGROUND Di-n-butyl phthalate (DBP), a chemical widely used in many consumer products, is estrogenic and capable of producing seriously reproductive and developmental effects in laboratory animals. However, recent in vitro studies have shown that DBP and mono-n-butyl phthalate (MBP), the major metabolite of DBP, possessed thyroid hormone receptor (TR) antagonist activity. It is therefore impo...
The serum mannan-binding protein (MBP) is a host defense C-type lectin specific for mannose, N-acetylglucosamine, and fucose residues, and exhibits growth inhibitory activity toward human colorectal carcinoma cells. The MBP-ligand oligosaccharides (MLO) isolated from a human colorectal carcinoma cell line, SW1116, are large, multiantennary N-glycans with highly fucosylated polylactosamine-type ...
The mld mutation is a complex genetic lesion affecting the myelin basic protein (MBP) locus in the mouse. The mutation consists of a variety of DNA rearrangements including: tandem duplication of the MBP structural gene, partial inversion of the 3' end of the upstream gene copy, duplication of a region flanking the rearrangement junction in the upstream copy and insertion between the two gene c...
We initially identified c-myc promoter-binding protein 1 (MBP-1) from a human cervical carcinoma cell expression library which negatively regulates c-myc promoter activity. A recent study demonstrated that MBP-1 acts as a general transcriptional repressor (A. K. Ghosh, R. Steele, and R. B. Ray, Mol. Cell. Biol. 19:2880-2886, 1999). In order to identify the cellular protein(s) interacting with M...
A frequent characteristic of immediate hypersensitivity reactions is systemic or localized tissue eosinophilia (1). This response is attributed to mast cell and basophil release of acidic tetrapeptides (2-4) and other products (5) preferentially chemotactic for eosinophils. Because of this association and eosinophil release of histaminase (6) and other mediators (7, 8) that may dampen allergic ...
هدف: در این مطالعه اثرات ویتامین D3 بر غلظت کل پروتئین و بیان پروتئین اصلی میلین (MBP) در جسم پینهای مغز موشهای دمیلینه شده توسط کاپریزون تحقیق شد. مواد و روشها: جهت القا دمیلینه شدن، موشها برای پنج هفته با کاپریزون تیمار شدند. سپس موشها به سه گروه تقسیم شدند. به اولین گروه از طریق داخل صفاقی ویتامین D3 به میزان 5 میکروگرم بر کیلوگرم وزن ...
Background and purpose: Oligodendrocytes are responsible for myelin synthesis in the central nervous system (CNS). Olig1 and Olig2 play an important role in regulating the development of oligodendrocyte precursor cells (OLPs). Myelin basic protein (MBP) is the main component of myelin sheath. Leukemia inhibitory factor (LIF) has an important role in myelination and pathology of multiple scleros...
