Yes; in the same way you can influence gravity by a spinning mass, albeit we do not possess (by orders of magnitude) material or energy required to spin a mass fast enough to detect an effect. Spinning supermassive blackholes show a gravitation/time frame-dragging effect dependent on speed of spin. Showing it occurs with EM is amazing.

This is probably a really dumb question but could this effect be the cause of the discrepancy of the expected and observed rotational velocity of galaxies?
