Notes:
Two distinct cDNAs encoding thyroid hormone receptors (THRs) were cloned from a λ gtl0 library prepared from the whole bodies of metamorphosing flounder larvae (Paralichfhys olivaceus). Deduced amino acid sequences of the two isolated cDNAs shared 96% and 92% homologies in their DNA- and hormone-binding domains, respectively. These were highly conserved when compared to THRs for other vertebrates: 88-96% in the DNA-binding domain and 84-94% in the hormone-binding domain. Other receptors in the nuclear receptor family showed lower homologies than those of THRs. Both THRs for the flounder had higher homologies with the α-type THRs of other vertebrates than with the β-type. Thus, the two THRs for flounder were designated as fTHRαA and fTHRαB. © 1994 Wiiey-Liss, Inc.
