The TSH receptor is a member of the G protein - coupled receptor superfamily of integral membrane proteins and is coupled to the G protein . </P> <P> It is primarily found on the surface of the thyroid epithelial cells, but also found on adipose tissue and fibroblasts . The latter explains the reason of the myxedema finding during Graves disease . </P>
