Proteinase 3

Proteinase 3 also known as PRTN3 is an enzyme that in humans is encoded by the PRTN3 gene.[1]

Function

Function

PRTN3 is a serine protease enzyme expressed mainly in neutrophil granulocytes. Its exact role in the function of the neutrophil is unknown, but, in human neutrophils, proteinase 3 contributes to the proteolytic generation of antimicrobial peptides. It is also the target of anti-neutrophil cytoplasmic antibodies (ANCAs) of the c-ANCA (cytoplasmic subtype) class, a type of antibody frequently found in the disease granulomatosis with polyangiitis (formerly known as “Wegener’s granulomatosis”).[2]
