Just to nitpick, you don't have TPTK. Villain can definitely r/c AK pre, it's not an automatic 4bet, especially in position.

Obviously your hand is good enough to value bet flop and turn here though. River, we can either c/c to induce bluffs or bet, if it's the latter I'd like a 1/3 river bet. I probably c/c my AQ and bet my AK, largely because I don't want to call AQ to a river jam. I'm not thrilled with AK facing a river jam either and should probably fold that too but when we have AK we're beating AQ and we don't block it quite so hard as we do right now, so there's more value.
