I remember an old boring discussion about dubstep & turntablism at dubstepforum.
Many purists said "noooo, there is no room for turntablism in dubstep, etc etc" at that time.
Now, we got two late answers for those purists; first a short video from Dubspot's DJ Shiftee that is prepeared for Native Instruments, and a nearly 30 mins mix from X-Kutz.
The answer is obvious; everything fits with dubstep if it's nicely done.
