Furin

== Function

Furin or proprotein convertase furin or dibasic-processing enzyme or paired basic amino acid residue-cleaving enzyme or PACE is a member of the proprotein convertase family and promotes the proteoplytic maturation of proproteins. Furin cleaves precursor proteins at their paired basic amino acid processing sites^[1].

Relevance

High furin activity promotes the malignant phenotype of cancer cells in head and neck squamous cell carcinoma, breast cancer and ^[2]. Furin has a role in atherosclerosis^[3]. The new coronavirus SARS-CoV19 genome sequence shows a furin-like cleavage site in the spike protein. This cleavage site has potential implications in the development of antivirals^[4].
