Abstract
We report here the characterization of restrictin, a novel chick neural extracellular matrix glycoprotein associated with the cell recognition molecule F11. Immunoaffinity chromatography using monoclonal antibody 23-13 directed to restrictin yield a major relative molecular mass band at 170 x 10(3) and minor bands at 160, 180, 250 and 320 x 10(3) which are immunologically related to each other. Neural cells attach on immobilized restrictin in a short-term adhesion assay. This adhesion can be blocked specifically by monoclonal or polyclonal antibodies to restrictin but not by antibodies to F11 or by the peptide GRGDSP. Antibodies to restrictin do not interfere with the fasciculation of retinal axons and the isolated restrictin does not stimulate the outgrowth of axons. In the developing nervous system, restrictin is localized in very restricted regions and is found within areas of F11 expression. The timing and pattern of expression of restrictin and its cell attachment activity suggest that it participates in developmental events of the nervous system.
