We measured the expression of γ2 GABAAR subunits in the fractions as an indirect measure of intact GABAAR localization, owing to the role of the γ2 subunit in synaptic targeting via its interaction with GABAAR-associated protein, GABARAP, an essential component of the GABAAR trafficking machinery.52, 53, 55, 56, 57 We found no difference in γ2 GABAAR subunit expression in the ER or SYN fractions between schizophrenia and comparison subjects. Here, GABARAP is linked to schizophrenia.
