Serine Endoprotease Furin (Furin)

Target
Furin
Molecular classification
Enzyme, Serine Protease, Subtilisin-like proprotein convertase
01

Overview

Furin is a calcium-dependent serine endoprotease primarily located in the Golgi apparatus. It belongs to the subtilisin-like proprotein convertase family and is responsible for processing precursor proteins into their active forms by cleaving at paired basic amino acid sites. Furin plays a crucial role in activating numerous proproteins involved in diverse biological processes, including hormone maturation, growth factor activation, and viral pathogenesis. Aberrant furin activity is implicated in various diseases, making it a potential therapeutic target.
