Abstract

The N-terminal globular domain of the laminin alpha1 chain binds to alpha1beta1 and alpha2beta1 integrins and to the heparan sulfate-containing domains of perlecan.

ABSTRACT: The N-terminal domains VI plus V (62 kDa) and V alone (43 kDa) of the laminin alpha1 chain were obtained as recombinant products and shown to be folded into a native form by electron microscopy and immunological assays. Domain VI alone, which corresponds to an LN module, did not represent an autonomously folding unit in mammalian cells, however. Fragment alpha1VI/V, but not fragment alpha1V, bound to purified alpha1beta1 and alpha2beta1 integrins, to heparin, and to heparan sulfate-substituted domains I and V of perlecan. This localized the binding activities to the LN module, which contains two basic sequences suitable for heparin interactions.
