Studies were performed to investigate the prohormone/proprotein convertase (PC)-inhibitory properties of chemical constituents of the medicinally active plant Andrographis paniculata (AP; from the family Acanthaceae), also known as 'King of Bitters'. Among the individual components tested against the clinically important convertases, furin and PC1, neoandrographolide (a C3 O-glucoside derivativ...
BACKGROUND Increases in plasma B-type natriuretic peptide (BNP) concentrations in those with acutely decompensated heart failure (ADHF) has been mainly attributed to an increase in NPPB gene transcription. Recently, proBNP glycosylation has emerged as a potential regulatory mechanism in the production of amino-terminal (NT)-proBNP and BNP. The aim of the present study was to investigate proBNP ...
Mammalian prosomatostatin (PSS) is cleaved at a dibasic Arg-Lys site to produce somatostatin-14 (SS-14) and at monobasic Arg and Lys sites to yield SS-28 and PSS(1-10) (antrin), respectively. Furin, PC1, and PC2 are three recently discovered mammalian endoproteases localized either to the constitutive (furin) or regulated (PC1, PC2) secretory pathways. In this study we have compared the heterol...
Purpose: Astrocytoma arises in the central nervous system as a tumor of great lethality, in part because of the invasive potential of the neoplastic cells that are able to release extracellular matrix-degrading enzymes. Furin convertase activates several precursor matrix metalloproteases involved in the breakdown of the extracellular matrix. In the present study inhibition of furin was achieved...
Many viral proteins undergo proteolytic processing events that are required for virus infection and virion assembly. In this issue of Biochemical Journal, Strongin and co-workers report that the NS3 protease from West Nile virus unexpectedly cleaves certain substrates at pairs of basic residues, a specificity that resembles that of the furin-like PCs (proprotein convertases). This led to the de...
Background Due to their osteoinductive properties, recombinant human bone morphogenetic proteins (rhBMPs) have been used successfully for bone regeneration and replacement. However, the yields rhBMPs yields in mammalian expression systems are very low, resulting in their high cost. BMPs are synthesized as a precursor, proBMP, which undergoes enzymatic cleavage by proprotein convertases (PCs) to...
We describe in this study a strategy to produce synthetic vaccines based on a single polypeptide capable of eliciting strong immune responses to a combination CTL and Th epitopes with the purpose of treating malignancies or preventing infectious diseases. This strategy is based on the capacity of Trojan Ags to deliver exogenous Ags into the intracellular compartments, where processing into MHC-...
BACKGROUND Before furin can act on protein substrates, it must go through an ordered process of activation. Similar to many other proteinases, furin is synthesized as a zymogen (profurin) which becomes active only after the autocatalytic removal of its auto-inhibitory prodomain. We hypothesized that to activate profurin its prodomain had to be removed and, in addition, the emerging enzyme's N-t...
Crimean-Congo hemorrhagic fever virus (genus Nairovirus, family Bunyaviridae) genome M segment encodes an unusually large (in comparison to members of other genera) polyprotein (1,684 amino acids in length) containing the two major structural glycoproteins, Gn and Gc, that are posttranslationally processed from precursors PreGn and PreGc by SKI-1 and SKI-1-like proteases, respectively. The char...
