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.

Cofactor

Calcium By similarity.

Enzyme regulation

Could be inhibited by the not secondly cleaved propeptide.

Subunit structure

Interacts with FLNA. Binds to PACS1 which mediates TGN localization and connection to clathrin adapters By similarity.

Subcellular location

Golgi apparatustrans-Golgi network membrane; Single-pass type I membrane protein. Cell membrane; Single-pass type I membrane protein. Note: Shuttles between the trans-Golgi network and the cell surface. Propeptide cleavage is a prerequisite for exit of furin molecules out of the endoplasmic reticulum (ER). A second cleavage within the propeptide occurs in the trans Golgi network (TGN), followed by the release of the propeptide and the activation of furin.

Tissue specificity

Seems to be expressed ubiquitously.

Domain

Contains a cytoplasmic domain responsible for its TGN localization and recycling from the cell surface.

Post-translational modification

The inhibition peptide, which plays the role of an intramolecular chaperone, is autocatalytically removed in the endoplasmic reticulum (ER) and remains non-covalently bound to furin as a potent autoinhibitor. Following transport to the trans Golgi, a second cleavage within the inhibition propeptide results in propeptide dissociation and furin activation.

Phosphorylation is required for TGN localization of the endoprotease. In vivo, exists as di-, mono- and non-phosphorylated forms By similarity.

Sequence similarities

Belongs to the peptidase S8 family. Furin subfamily.

Contains 1 homo B/P domain.
