Product details:
Abcam's Furin Human ELISA (Enzyme-Linked Immunosorbent Assay) kit is an
in vitro
enzyme-linked immunosorbent assay for the quantitative measurement of Human Furin in serum, plasma (collect plasma using heparin and EDTA as an anticoagulant. Citrate is not recommended) and cell culture supernatants.
This assay employs an antibody specific for Human Furin coated on a 96-well plate. Standards and samples are pipetted into the wells and Furin present in a sample is bound to the wells by the immobilized antibody. The wells are washed and biotinylated anti-Human Furin antibody is added. After washing away unbound biotinylated antibody, HRP-conjugated streptavidin is pipetted to the wells. The wells are again washed, a TMB substrate solution is added to the wells and color develops in proportion to the amount of Furin bound. The Stop Solution changes the color from blue to yellow, and the intensity of the color is measured at 450 nm.
Optimization may be required with urine samples.

Furin is a serine endoprotease that plays critical role in the cleavage of precursor proteins into their active forms. It belongs to the proprotein convertase family and is also known as furin protease. The molecular weight of furin is approximately 54 kDa. Furin is ubiquitously expressed in various tissues in the body with high expression levels in the liver and the central nervous system. Furin is mainly located in the trans-Golgi network where it processes many precursor proteins involved in various cellular functions.
Biological function summary
Furin processes precursor proteins by cleaving at specific sequence motifs. This activity is essential for the maturation of many hormones growth factors and receptors. Furin is not part of a larger complex; it functions independently in its proteolytic activity. The processing by furin ensures that proteins become functional affecting numerous biological processes across different cell types and tissues.
Pathways
The activity of furin impacts the regulation of the Notch signaling pathway and the MAPK/ERK pathway. In the Notch signaling pathway furin processes Notch receptors facilitating their activation and downstream signaling. In the MAPK/ERK pathway furin activates several key proteins including growth factors and receptors essential for cell proliferation and differentiation. Furin-related proteins such as convertase enzymes are part of a similar family having roles in overlapping or complementary pathways.
Furin is implicated in several conditions including cardiovascular diseases and certain cancers. In cardiovascular diseases furin's role in processing proteins such as pro-BNP may have implications in cardiac function and disease progression. In cancer altered furin activity can lead to the inappropriate activation of growth factors and receptors contributing to tumor progression. Furin inhibitors are researched for their potential to modulate furin activity in these diseases and provide therapeutic benefits.
