Signaling Architectures that Transmit Unidirectional Information Despite Retroactivity

(Biophysical Journal 113, 728–742; August 8, 2017)

Page 734, column 2, line 7 should read:

However, if X_T (and M_T) is made small, the system cannot attenuate the retroactivity to the output, since as the output X^∗∗ is sequestered by the downstream system, there is not enough substrate available for the signaling system.
