Cloning and characterization of a naturally occurring soluble form of TGF-b type I receptor

Cloning and characterization of a naturally occurring soluble form of TGF-β type I receptor.

Transforming growth factor-β1 (TGF-β1) has been implicated to play an important role both in the process of normal development and in the pathogenesis of a wide variety of disease processes, including those of the kidney. TGF-β1 regulates diverse cellular functions via a heteromeric signaling complex of two transmembrane serine/threonine kinase receptors (types I and II). Several distinct type ...

Bacterial Expression and Functional Characterization of A Naturally Occurring Exon6-less Preprochymosin cDNA

Chymosin (Rennin EC 3.4.23.4), an aspartyl proteinase, is the major proteolytic enzyme in the fourthstomach of the unweaned calf, and it is formed by proteolytic activation of its zymogene, prochymosin.Following the cloning of synthesized cDNAs on mRNA pools extracted from the mucosa of the calf fourthstomach, we have identified an alternatively spliced form of preprochymosin ...

Detection, Cloning, Molecular Characterization and Phylogenic Analyses of a New Primate T-Cell Lymphotropic Virus Type I in Olive Baboon

Directed Blocking of TGF-β Receptor I Binding Site Using Tailored Peptide Segments to Inhibit its Signaling Pathway

Background: TGF-β isoforms play crucial roles in diverse cellular processes. Therefore, targeting and inhibiting TGF-β signaling pathway provides a potential therapeutic opportunity. TGF-β isoforms bind and bring the receptors (TβRII and TβRI) together to form a signaling complex in an ordered manner. Objectives: Herein, an antagonistic variant of TGF-β (AnTβ)...

Fusion of Cholera toxin B subunit (ctxB) with Shigella dysenteriae type I toxin B subunit (stxB), Cloning and Expression that in E. coli

Background and Objective: Shiga toxin (STx) is the main virulence factor in Shigella Dysenteriae type I and is composed of an enzymatic subunit STxA monomer and a receptor-binding STxB homopentamer. Shigella toxin B subunit (STxB) is a non-toxic homopentameric protein responsible for toxin binding and internalization into target cells by interacting with glycolipid (Gb3). Cholera toxi...
