You can't, it uses an own key scheme not compatible with openpgp. The
protocol is described on
https://github.com/WhisperSystems/TextSecure/wiki/ProtocolV2, they use
ECC with Curve25519 and AES256. Signatures on a key are not possible.
Only manual verification of the key fingerprint, or, when ypou meet in
person, scanning this number represented in a QR code on screen with the
camera, is possibble.

I use Textsecure quite some time as sms replacement but failed to
convinvce anyone else to use it too (wether as sms replacement or stand
alone chatapp).
