Background Information

FURIN, also named as FUR, PACE, PCSK3, SPC1, Kex2p, is likely to represent the ubiquitous endoprotease activity within constitutive secretory pathways and capable of cleavage at the RX(K/R)R consensus motif. Furin is synthesized as an inactive zymogen that may minimize the occurrence of premature enzymatic activity that would lead to alternative protein activation or degradation. Glycosylation and other post-translational modifications can make the pre-pro furin run at 100-110 kDa, the mature furin at 98-95 kDa and shed furin at 90 kDa.

Boyan (Verified Customer) (03-11-2019)

For WB, the expected band was strong; for IF, PFA fixation, it could label the cell surface-like localisation and the Golgi localisation of Furin.

  • Applications: Western Blot, Immunofluorescence,
  • Cell Tissue Type: MEF
