Figure 2From: Ultrasensitive Responses and Specificity in Cell SignalingMonotonic stimulus-response curves hinder mutual fidelity. (A) Pictorial representation of a network employing only ultrasensitive activation achieving Mutual Specificity (MS). (B) Pictorial representation of a network without cross regulation that cannot attain Mutual Fidelity (MF). (C) A network with cross-pathway inhibition that attains MF.Back to article page
