- 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 von Willebrand factor from their respective precursors.
- COFACTOR: Calcium (By similarity).
- ENZYME REGULATION: Could be inhibited by the not secondly cleaved propeptide.
- SUBUNIT: Interacts with FLNA (By similarity). Binds to PACS1 which mediates TGN localization and connection to clathrin adapters.
- SUBCELLULAR LOCATION: Golgi apparatus, trans-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 (By similarity).
- TISSUE SPECIFICITY: Seems to be expressed ubiquitously.
- DEVELOPMENTAL STAGE: Expressed at E7 day in endoderm and mesoderm, uniformly expressed until E10, when expression is higher in heart and liver primordia. In mid- and late-gestational stages, widely expressed.
- DOMAIN: Contains a cytoplasmic domain responsible for its TGN localization and recycling from the cell surface.
- PTM: 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 (By similarity).
- PTM: Phosphorylation is required for TGN localization of the endoprotease. In vivo, exists as di-, mono- and non-phosphorylated forms (By similarity).
- SIMILARITY: Belongs to the peptidase S8 family. Furin subfamily [view classification].
- SIMILARITY: Contains 1 homo B/P domain.
