  Recent progress in the microscopic description of rotational properties
within covariant density functional theory (CDFT) is presented. It is shown
that it provides an accurate description of rotational bands both in the paired
regime at low spin and in the unpaired regime at ultra-high spins. The
predictive power of CDFT is verified by comparing the CDFT predictions for band
crossing features in the $A\geq 242$ actinides with new experimental data. In
addition, possible role of the Coulomb antipairing effect for proton pairing is
discussed.
