  We apply the spin-fermion model to study the normal state and pairing
instability in electron-doped cuprates near the antiferromagnetic QCP. Peculiar
frequency dependencies of the normal state properties are shown to emerge from
the self-consistent equations on the fermionic and bosonic self-energies, and
are in agreement with experimentally observed ones. We argue that the pairing
instability is in the $d_{x^{2}-y^{2}}$ channel, as in hole-doped cuprates, but
theoretical $T_{c}$ is much lower than in the hole-doped case. For the same
hopping integrals and the interaction strength as in hole-doped materials, we
obtain $T_{c}\sim10$K at the end point of the antiferromagnetic phase. We argue
that a strong reduction of $T_{c}$ in electron-doped cuprates compared to
hole-doped ones is due to critical role of the Fermi surface curvature for
electron-doped materials. The $d_{x^{2}-y^{2}}$-pairing gap
$\Delta(\mathbf{k},\omega)$ is strongly non-monotonic along the Fermi surface.
The position of the gap maxima, however, does not coincide with the hot spots,
as the non-monotonic $d_{x^{2}-y^{2}}$ gap persists even at doping when the hot
spots merge on the Brillouin zone diagonals.
