We examine the threshold behavior of the deep inelastic electroproduction structure functions in a composite model field theory. We find that the high rank behavior of hadron matrix elements of the tensor operators, which appear in the light-cone expansion of current product, leads to a reasonable threshold behavior on the structure functions and that the Drell-Yan-West relation holds if the anomalous dimension is neglected. In calculating the matrix elements we have used properties of the Bethe-Salpeter amplitude which are obtained via the conformal-covariant light-cone expansion for the product of the fields constituting the bound state.
