Protein attributes

Sequence length	783 AA.
Sequence status	Complete.
Sequence processing	The displayed sequence is further processed into a mature form.
Protein existence	Evidence at transcript level.

General annotation (Comments)

Function	Furin is likely to represent the ubiquitous endoprotease activity within constitutive secretory pathways and capable of cleavage at the RX(K/R)R consensus motif.
Catalytic activity	Release of mature proteins from their proproteins by cleavage of -Arg-Xaa-Yaa-Arg-|-Zaa- bonds, where Xaa can be any amino acid and Yaa is Arg or Lys. Releases albumin, complement component C3 and vWF from their respective precursors.
Subcellular location	Membrane; Single-pass membrane protein Potential.
Tissue specificity	In all tissues analyzed.
Sequence similarities	Belongs to the peptidase S8 family. Furin subfamily.
