Background: Furin

Furin is a member of the proprotein convertase (PC) family, which belongs to the subtilisin superfamily of serine protease (1-3). As a cellular protease, Furin cleaves after Arg-Xaa-Lys/Arg-Arg-like motifs typically at the end of the pro region in a variety of proproteins within the secretory pathway including growth factors and receptors, extracellular matrix proteins, and other proteases. Through regulation of proprotein maturation, Furin has an essential role in embryogenesis and homeostasis and is implicated in various pathologies such as cancer (4), neurodegenerative diseases (5) and infectious disease (6). Furin is synthesized as a 794 amino acid type I transmembrane protein precursor with a signal peptide (residues 1-24), a pro region (residues 25-107) that plays a crucial role in the folding, activation and transport of Furin, and a mature chain (residues 108-794) (1-3). The mature chain consists of the subtilisin-like catalytic domain, a P domain, which is essential for enzyme activity and the modulation of pH and calcium requirements, and a cytoplasmic domain, which controls the localization and sorting of Furin in the trans-Golgi network/endosomal system. The purified recombinant human Furin corresponds to a truncated form of the mature enzyme terminated before the transmembrane domain.
