We extend the MRS(A) set of parton distributions, which provides an up-to-date description of the structure of the proton probed by hard interactions, into the region of ${\mathit{Q}}^{2}$ below 5 ${\mathrm{GeV}}^{2}$. After physically motivated modifications, we obtain a smooth description of the data on the structure function ${\mathit{F}}_{2}$(x,${\mathit{Q}}^{2}$) all the way from ${\mathit{Q}}^{2}$=${10}^{\mathrm{\ensuremath{-}}1}$ to ${10}^{3}$ ${\mathrm{GeV}}^{2}$.
