During decent on the RNP X approach to Runway XXR we received a 'caution terrain' warning. The First Officer; who was pilot flying immediately disengaged the autopilot; and stopped the descent; and turned to steepen up the turn away from the terrain. We were approaching the waypoint ZZZZZ. The remainder of the approach; and landing proceeded normally. It was still daylight; and we were in VMC conditions.I failed to see the company NOTAM that stated the RNP X XXR was unusable. I had made a similar RNP approach recently to ZZZ1 landing west; but now realize that was to XXL; not XXR. I was feeling rushed in ZZZ; and the release was brought out to the plane late in the boarding process. I still should have taken the time to read; and understand ALL of the release. It might be helpful also; if the company could have Jeppesen print on the plates that are NOTAMed out some sort of warning. Perhaps making it not selectable in the FMS would be helpful too.
Q400 flight crew reported flying an approach that was NOTAMed out of service; resulting in a terrain warning.
