Research Abstract |
A new extracellular matrix protein of 36 kDa has been purified from bovine and porcine aorta. The protein, 36 kDa microfibril associated glycoprotein (36kDa - MAGP), has a fibrinogen - like domain and contained the sequence Arg - Gly - Asp in the N - terminal region, which is the site for the association with cell and extracellular matrix. Immunoelection microscopy specified its location to elastin - microfibrils. Using Ca^<2+> - dependent affinity chromatography on an isoquinoline sulfonamide (CKA 1303 ) coupled agarose, we obtained pure form of 36 kDa -MAGP.This compound should serve as a useful tool for clarifying the physiological roles of 36 kDa - MAGP.During the synthesis and selection of S - 100 protein antagonists derived from cinnamic acid and anthranilic acid, we discovered that N - acetyl anthranilic acid and O - (3', 4' - dimethoxy cinnamoyl) salicilic acid strongly bind to 36kDa-MAGP.
