Abstract
We have identified a member of the steroid receptor superfamily and cloned it from human and rat hypothalamus, prostate, and testis cDNA libraries. The open reading frame between first ATG and terminator TGA can encode 615 (human) and 596 (rat) amino acids with calculated molecular mass of 67.3 (human) and 65.4 (rat) kDa. The amino acid sequence of this protein, called TR4 orphan receptor, is closely related to the previously identified TR2 orphan receptor. The high homology between TR2 and TR4 orphan receptor suggests that these two orphan receptors constitute a unique subfamily within the steroid receptor superfamily. These two orphan receptors are differentially expressed in rat tissues. Unlike TR2 orphan receptors, the TR4 orphan receptor appears to be predominantly located in granule cells of the hippocampus and the cerebellum, suggesting that it may play some role(s) in transcriptional regulation in these neurons.
