Furin cleavage sites naturally occur in coronaviruses

13-P113 Mutation of Furin cleavage sites in Drosophila BMPs

Gli repressor formation via Protein kinase A (PKA) activation. In the current study, we generated a chondrocyte-specific knockout mouse strain of Suppressor of Fused (Sufu) and demonstrated that loss of Sufu leads to elevated expression of Hh target genes, Gli1 and Patched 1 (Ptch1), in the growth plate. Histological analysis illustrated an increase of proliferating cells and a reduction of the...

Positively Selected Sites at HCMV gB Furin Processing Region and Their Effects in Cleavage Efficiency

Human cytomegalovirus is a ubiquitous infectious agent that affects mainly immunosuppressed, fetuses, and newborns. The virus has several polymorphic regions, in particular in the envelope glycoproteins. The UL55 gene encodes the glycoprotein B that has a variable region, containing a furin cleavage site and according to the variability different genotypes are characterized. Here we investigate...

Computational prediction of furin cleavage sites by a hybrid method and understanding mechanism underlying diseases

Furin cleaves diverse types of protein precursors in the secretory pathway. The substrates for furin cleavage possess a specific 20-residue recognition sequence motif. In this report, based on the functional characterisation of the 20-residue sequence motif, we developed a furin cleavage site prediction tool, PiTou, using a hybrid method composed of a hidden Markov model and biological knowledg...

High-Resolution Analysis and Functional Mapping of Cleavage Sites and Substrate Proteins of Furin in the Human Proteome

BACKGROUND There is a growing appreciation of the role of proteolytic processes in human health and disease, but tools for analysis of such processes on a proteome-wide scale are limited. Furin is a ubiquitous proprotein convertase that cleaves after basic residues and transforms secretory proproteins into biologically active proteins. Despite this important role, many furin substrates remain u...
