| Sumario: | The present paper is the first report on the existence in marine scallops of a protein with properties similar to those of mammalian fibronectin (FN), henceforth called a scallop fibronectinlike polypeptide (sFN-LP). We describe the results of the biochemical and immunochemical identification of sFN-LP in mature gonad tissue of the simultaneous hermaphroditic species Pecten maximus (L., 1758). sFN-LP is similar to mammalian FN in the following respects: (1) it is a dimeric polypeptide with subunits of approx. 200 kDa; (2) it is recognised by antibodies against human FN on Western-blots; and (3) it is located in the basement membranes of follicles, the connective-tissue matrix, and the integument of the gonad. In the P. maximus female gonad compartment, sFN-LP is highly accumulated in the connective-tissue fibrilar network but is not detected in oocytes. In the male gonad tissue, only trace amounts of sFN-LP were detected. |
