Localization of the binding site for cell attachment in the alpha1(I) chain of collagen
Open accessAbstract
Certain cells such as CHO (Chinese hamster ovary) and fibroblasts attach to a substrate of type I collagen via proteins that link the cell surface to collagen. Serum contains a glycoprotein, c-CAP (collagen cell attachment protein), that can mediate this adhesion. Previously, we established that alpha1(I)-CB7 (cyanogen bromide peptide 7), which lies within residues 552 to 822 of collagen, contains a major binding site for c-CAP(alpha1(I)-CB7 has been renumbered to account for an additional triplet recently identified at residue 613 (P. P. Fietzek and R. W. Glanville, manuscript in preparation). Now we have examined the ability of various peptides derived by proteolytic digestion of alpha1(I)-CB7 to bind to c-CAP based upon their ability to inhibit cell attachment to collagen. The binding site lies within residues 757 to 791. It is likely that this is the sole binding site in the alpha1(I) chain since cleavage of the bond between residues 775 and 776 in the alpha1(I) chain destroys cell attachment activity.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
