Detailed entry information

Protein Information (annotations from UniProt)

Database IDHIV0001111
UniProt IDP09958
Primary gene name(s)FURIN
Synonym gene name(s)FUR, PACE, PCSK3
Protein nameFurin
Protein functionFurin is likely to represent the ubiquitous endoprotease activity within constitutive secretory pathways and capable of cleavage at the RX(K/RR consensus motif. {ECO:0000269|PubMed:7690548}.
Subcellular locationGolgi 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.
