Here we investigated the effect of disruption of plasma membrane integrity by cholesterol depletion on thyrotropin-releasing hormone receptor (TRH-R) surface mobility in HEK293 cells stably expressing TRH-R-eGFP fusion protein (VTGP cells). The apparent diffusion coefficient (Dapp) was decreased, but this decrease was detectable only under the special conditions of screening and calculation of FRAP data. Decrease of cholesterol level impaired the functional coupling between the receptor and the cognate G proteins of Gq/G11 family
