Besides the brain, a cDNA for arrestin beta 2 was isolated from thyroid gland, and thus it may also be involved in hormone-specific desensitization of TSH receptors.
Pored mozga, cDNK za arestin beta 2 je bila izolovana iz tiroidne žlezde, i stoga on možda učestvuje u hormon-specifičnoj desenzitizaciji TSH receptora.
