Ras homolog enriched in striatum inhibits the functional activity of wild type thyrotropin, follicle-stimulating hormone, luteinizing hormone receptors and activating thyrotropin receptor mutations by altering their expression in COS-7 cells.

Abstract excerpt

Ras homolog enriched in striatum (Rhes) is a member of the Ras family of small GTPases detected in the thyroid. Rhes inhibits signal transduction from Galphas protein. In this study we investigated whether Rhes can interfere with stimulation of cAMP/protein kinase A (PKA) pathway of TSH, FSH and LH receptors (TSHr, FSHr, LHr) and of activated TSHr mutants. Receptors were transiently transfected in COS-7 cells...
