A, Conditions that altered Cx36 phosphorylation at Ser293 (D1R activation, SKF38393, 100 µM; D1R antagonism, SCH23390, 100 µM) had no effect on the size of Cx36 plaques in AII amacrine cells. Inhibition of PKA (Rp-8-CPT-cAMPS, 20 µM) also had no effect on Cx36 plaque size. B, Conditions that altered Cx36 phosphorylation at Ser293 (D1R activation, SKF38393, 100 µM; D1R antagonism, SCH23390, 100 µM) had no effect on the overall distribution of Cx36 plaques in AII amacrine cells. Inhibition of PKA (Rp-8-CPT-cAMPS, 20 µM) also had no effect on Cx36 plaque distribution. Error bars are s.e.m, n = 5. No significant changes were found.
