General description

Fibrinopeptide B (FPB) is produced during the cleavage of fibrinogen, by thrombin, to fibrin monomer. It is cleaved off from the N-terminal of the fibrinogen β chain. This peptide is composed of 14 amino acids.

Biochem/physiol Actions

Cleavage of fibrinopeptide B from fibrinogen Bβ chains exposes E domain polymerization sites, E(B), that interact with platelets, fibroblasts and endothelial cells.
Fibrin formation is an essential part in wound healing and inflammation. Fibrinopeptide B (FPB) can also cause chemotactic migration of neutrophils, without the simultaneous release of lysosome enzymes. It is produced during the coagulation of fibrinogen, which is essential for physiological homeostasis. It is involved in various disorders such as thrombosis and disseminated intravascular coagulation.

A sample preparation method for protein C-terminal peptide isolation has been developed. In this strategy, protein carboxylate glycinamidation was preceded by carboxyamidomethylation and optional α- and ϵ-amine acetylation in a one-pot reaction, followed by tryptic digestion of the modified protein.

Thrombin (IIa)-cleavage of fibrinogen (FBG) to form polymerized fibrin promotes endothelial cell spreading, proliferation, and von Willebrand factor release, requiring the exposure of the beta 15-42 domain. Studies reported here indicate that IIa-cleavage of fibrinopeptide B enhances exposure of a

Biomarkers that evaluate the response to erythropoietic-stimulating agents largely measure inflammation and iron availability. While these are important factors in modifying an individual's response to these agents, they do not address all aspects of a poor response. To clarify this

Liquid chromatography coupled to tandem mass spectrometry (LC-MS/MS) with selective reaction monitoring (SRM) is a selective and sensitive method for quantitation of peptides. SRM is achieved via MS/MS utilizing collision-induced dissociation (CID) while monitoring unique precursor-product ion transitions. Low-energy CID
