| Product Introduction |
Furin, a member of the proprotein convertase (PC) family, belongs to the subtilisin superfamily of serine proteases. As an intracellular protease, Furin specifically cleaves after Arg-Xaa-Lys/Arg-Arg motifs at the C-terminus of pro-regions in various proproteins within the secretory pathway—including growth factors, receptors, extracellular matrix proteins, and other proteases—to facilitate their maturation. Additionally, many other cellular proteins, certain viral proteins, and bacterial toxins transported via the constitutive secretory pathway also rely on PC family enzymes for proteolytic processing. Furin and other PC family members share conserved structural features: . A heterogeneous ~10 kDa N-terminal prodomain. A highly conserved ~55 kDa subtilisin-like catalytic domain. A C-terminal domain with variable length and sequence. In mammalian cells, furin is localized mainly to the trans‑Golgi network and endosomal compartments, where it functions in the secretory and endocytic pathways under mildly acidic to neutral pH conditions. |
