Figure 2. Phosphorylation dependence is little affected by site-1 and site-2 mutations. (AâD) Inward chloride currents recorded in patches excised from resting oocytes expressing WT (A), F1296S (B), N1303Q (C), and F1296S/N1303Q (D) CFTR. In each case, the application of 2 mM ATP (bars) elicits only small currents relative to those activated by subsequent exposure to 300 nM PKA plus 2 mM ATP (bars). Note the rapid partial deactivation after the removal of PKA in AâD and the persistent channel activity after the removal of ATP in D (magnified in inset). Membrane potential was â80 mV in AâC, but â20 mV in D. Image published in: Szollosi A et al. (2010) © 2010 Szollosi et al.
