We analyze electroproduction of ø-meson from a proton within a uud-sS cluster model as a probe of the strangeness content of the proton. Our consideration is based on the relativistic harmonic oscillator quark model which takes into account the Lorentz-contraction effect of the hadron wave functions. We show that the knockout mechanisms are comparable to the vector-meson-dominance model of diffractive production if only (l-2)% st rang e quark admixture is assumed. The uud- and ss-knockout cross sections have a qualitatively different dependence on the four-momentum transfer squared to the proton and may be distinguished experimentally.
