  A resonance search has been made in the K^{0}s-p, K^{0}s-pbar and K^{+}p
invariant-mass spectra measured with the ZEUS detector at HERA using an
integrated luminosity of 121 pb^{-1}. The search was performed in the central
rapidity region of inclusive deep inelastic scattering at an ep centre-of-mass
energy of 300--318 GeV for exchanged photon virtuality, Q2, above 1 GeV^{2}.
The results support the existence of a narrow state in K^{0}s-p and K^{0}s-pbar
decay channels, consistent with the pentaquark prediction. No signal was found
in the K^{+}p$ decay channel.
