Abstract: Charm production has been measured with the ZEUS detector in deep inelastic ep scattering at HERA. The measurement is based on the full reconstruction of the decay chain \newline $D^{*}$ $\rightarrow$ $D^{0} $ $\pi$, $D^{0}$ $\rightarrow$ K $\pi$ and exploits the full HERA II statistics with integrated luminosity \textit{L} = 357 $\text{pb}^{-1}$ . Differential cross-sections have been measured. The kinematic range is 1.5 GeV $ < $ $P_{t}$(D*) $ < $ 20 \,GeV, $|\eta($D*$)|$ $ < $ 1.5, 5 $ < $ $Q^{2}$ $ < $ 1000 \, $GeV^{2}$ and 0.02 $ < $ y $ < $ 0.7. The observed cross sections were extrapolated to the full $P_{t}$(D*) and $\eta$(D*) range in order to determine the open-charm contribution, $F_{2}^{c\bar{c}}$(x,$Q^{2}$) to the proton structure function $F_{2}$.
