Protease nexin-I (
PN-I
, Mr approximately 43,000) is representative of a newly described class of cell-secreted protease inhibitors.
PN-I
has been purified to apparent homogeneity, partially sequenced, and monospecific antibodies have been raised against it.
PN-I
is a potent inhibitor of urokinase, thrombin, plasmin, and
trypsin
. In addition, cells have specific receptors that mediate the uptake of covalently linked complexes formed between
PN-I
and its protease substrates. In the present studies, we have investigated the relationship between human
PN-I
and a protease inhibitor derived from C6 glioma cells in culture that has neurite-promoting activity. On the basis of co-purification on heparin-Sepharose, identical molecular weight, antibody cross-reactivity, and receptor cross-reactivity, we conclude that
PN-I
and the glioma-cell-derived inhibitor are equivalent molecules.
