this suggests that events other than ligand binding can result in formation of a c-erba protein that modulates transcription of thyroid hormone responsive genes , 3 ) no qualitative functional differences were detected between alpha- and beta-c-erba subtypes , and 4 ) depending on the cell-type , l-t3 acts through its endogenous receptor to stimulate ( gh4c1 ) or suppress ( gh1 ) expression of a chimeric prl construct .
