No because Pro tools first of all uses different raw file format, second they both use different modules to create sounds. Reason has its own modules such as NN19, DrRex etc, however Pro Tools has their own VST format, which isnt even familiar with Cubase or Sonar as far as i know.
Your best bet is exporting each layer in MIDI, and Audio and then importing it into Pro Tools as the studio (which i wouldnt bother doing because it wont sound the same).
If your just wanting to master you track at the studio in pro tools then you can export each layer as .wav and then allowing for mastering of each track.
