I don't agree. I don't have my original source for that receptor correlation but I did find this:
https://www.sciencedirect.com/topics/neuroscience/muscimol
Muscimol is a conformationally restricted analog of GABA in which a hydroxyisoxazole moiety replaces the carboxyl group of GABA. The 3-hydroxyisoxazole is recognized as a carboxyl group equivalent by GABAA and GABAC receptors but not by GABABreceptors. The neuronal GABA uptake system recognizes the 3-hydroxyisoxazole moiety, in that muscimol is a weak inhibitor of GABA uptake but is neither an inhibitor of nor a substrate for GABA aminotransferase, indicating that this enzyme does not interact with the 3-hydroxyisoxazole moiety.
I didnt argue you on that point, i mean the dotted line should point to the carbon not nitrogen, this is the same as what the reference mentioned.
Lemme draw picture:
