SUBCELLULAR LOCALIZATION	extracellular
	plasma membrane
	intracellular
	intracellular,cytoplasm,cytosolic,vesicle
text	delivered to the plasma membrane, apparently together with TGOLN2 in the same vesicles, which after fusion with the membranes released cargo

basic FUNCTION	serine proteinase inhibitor
	plasminogen activator inhibitor type 2
	inhibit extracellular matrix degradation by PLAU (urokinase inhibitor)
	regulation of Th1 responses appears to be a physiological function of inflammation-associated SERPINB2
	enzyme inhibitor which is involved in various biological processes including cell differentiation, tissue regrowth and regeneration
	has a role for promoting the differentiation of epidermal keratinocytes
	in endothelial cells SERPINB2 induced with inflammatory stimuli, can inhibit proteasome and thus tilt the balance favoring proapoptotic signaling
	its extracellular concentration significantly increases during inflammation

INTERACTION

DNA

RNA

small molecule

protein	potent inhibitor of urokinase-type plasminogen activator (PLAU) and also acts as a multifunctional protein
	physiological interaction between RB1, RBL2 and SERPINB2
	is a cell survival factor that modulates RB1 repression of proapoptotic signal transduction
	while SERPINE1 and SERPINB2 function similarly in the control of cellular plasmin generation by PLAT, they may have disparate effects on the alternative functions of PLAT via modulation of its engagement with endocytosis receptors
	interacts with proteasome and affects its activity in endothelial cells
	SERPINB2 and TGM2 are downstream mediators in the antiapoptotic response triggered upon TBK1 activation
	FOSB is the mediator of SERPINB2 transactivator function explaining the orientation dependence observed for SERPINB2 transactivator activity
	FOSB and JUN can derepress transcription from the SERPINB2 promoter which may have general significance for SERPINB2-expressing cells
	extracellular matrix-associated proteins vitronectin and plasminogen activator inhibitor-2 (SERPINB2) were identified as novel CHL1 interaction partners, promoting CHL1-induced neurite outgrowth and neuronal migration
