SUBCELLULAR LOCALIZATION	extracellular
	intracellular
	intracellular,nucleus

basic FUNCTION	inhibits the activity of cathepsin G (release of neutrophil cathepsin G can destroy the vascular matrix through degradation, platelet aggregation and coagulation disorders)
	inhibitor that controls proMMP-9 activation in skin tissue
	would likely contribute to reducing tissue damage by proteases that are released at the site of skin injury
	in the context of chronic inflammatory diseases, therapeutic SERPINA3 might protect tissue from undesirable destructive side effects of leukocyte-derived proteases
	is a typical acute-phase protein secreted into the circulation during acute and chronic inflammation
	has anti-inflammatory and anti-apoptotic functions
	importance of SERPINA3 in the homeostasis of placental development
