Example sentences for: heparin-binding
How can you use “heparin-binding” in a sentence? Here are some example sentences to help you improve your vocabulary:
Fibronectin contains three types of homology sequences, I-III; type I sequences bind heparin, Staphylococcus aureus, fibrin, and cell surfaces, type II sequences bind collagen and gelatin, and type III sequences bind DNA, cell surfaces, heparin, and fibulin-1 [ 40 43 ] . Fibulin-1 interacts with fibronectin through a heparin-binding region in type III 13 repeat; the binding of fibulin-1 to this site is independent of the binding of heparin as addition of exogenous heparin does not inhibit fibulin-1 binding to fibronectin [ 40 ] . The fibronectin-binding site in fibulin-1 is located in EGF-like modules 5 and 6 [ 44 ] ; the binding of fibulin-1 to fibronectin is a heterotypic interaction in which an EGF-like module binds to a non EGF-like domain (the type III 13 fibronectin repeat) [ 40 ] .
These negatively-charged EGF-like modules of LTBP-3 may interact efficiently with the positively-charged heparin-binding domain of both the membrane-bound and soluble forms of HB-EGF.
The precursor of heparin-binding EGF-like growth factor (proHB-EGF) is found on a wide variety of cell surfaces and is present in numerous tissue types [ 1 ] . Previously in our laboratory, we cloned the cDNA encoding proHB-EGF from monkey Vero cells and identified this cell-surface molecule as a receptor for diphtheria toxin (DT) [ 2 ] . The predicted amino acid sequence was shown to be identical to that of the cell surface-expressed precursor of human heparin-binding EGF-like growth factor (proHB-EGF) [ 3 4 ] . The derived amino acid sequence revealed a signal sequence (residues 1-23), an extracellular domain (residues 24-159), a transmembrane domain (residues 160-184), and a carboxyl terminal cytoplasmic domain (residues 185-208) [ 2 ] . Proteolytic processing of the proHB-EGF occurs on the cell surface and results in the release of mature HB-EGF (mHB-EGF) (residues 63-148) [ 5 ] . The mature/soluble HB-EGF is a member of the EGF family of growth factors that includes amphiregulin, epidermal growth factor, and transforming growth factor a [ 6 ] . Mature HB-EGF released from the cell surface is mitogenic and is able to bind to the EGF receptor [ 3 ] . Membrane-bound proHB-EGF has juxtacrine growth factor activity [ 7 ] and also acts as a DT receptor [ 2 8 ] .
The amino acid sequence of the heparin-binding region of HB-EGF ( 21KRKKKGKGLGKKRDPCLRKYK 41) [ 2 ] has been shown to have a strong affinity for heparin and may influence the interaction of this growth factor with cell-surface negatively charged heparan sulfate proteoglycans [ 22 ] . It remains to be seen whether specific/all of the EGF-like modules are required and whether calcium is needed for the interaction of HB-EGF with LTBP-3.
the EGF-like modules of fibulin-1C interacting with the heparin-binding region of fibronectin) or with EGF-like modules (e.g.
