Please wait a moment until all data is loaded. This message will disappear when all data is loaded.
histone
-
histones H1, H2A, H2B, H3, and H4 promote pro-plasma hyaluronan-binding protein autoactivation in vivo. Histones do not affect enzymatic activity of the active form of plasma hyaluronan-binding protein
hyaluronic acid
-
activates single-chain inactivate zymogen to the two-chain active enzyme
IL-8
-
can stimulate the expression of HABP mRNA in lung microvascular endothelial cells and in bronchial epithelial cells
-
LPS
-
stimulates FSAP mRNA expression 6fold after 1 h, reaching a plateau at 2 h (7fold stimulation) and gradually decreases until returning to the base level at 24 h
-
phosphatidylethanolamine
-
enhances autofragmentation and serine protease activity at 0.001 mg/ml and 0.00001 mg/ml
polyethylenimine
FSAP is exclusively activated by the positively charged surfaces polyethylenimine and poly-L-lysine
-
Dextran sulfate
-
strongly accelerates autoactivation, strongest acceleration at 0.02 mg/ml of 5-kDa-dextran sulfate
-
heparin
-
strongly accelerates autoactivation, optimum concentration: 5-10 U/ml, presence of 7.5 U/ml reduces the half-life of the proenzyme from 12 min to 3.5 min
heparin
-
activates single-chain inactivate zymogen to the two-chain active enzyme
poly-L-lysine
FSAP is exclusively activated by the positively charged surfaces polyethylenimine and poly-L-lysine
RNA
-
natural or artificial RNA is an effective cofactor for FSAP mediated platelet-derived growth factor-BB degradation, whereas the effect of DNA is weak
