Also known as: TRH-R1
Summary: Predicted to enable identical protein binding activity and thyrotropin-releasing hormone receptor activity. Predicted to be involved in phospholipase C-activating G protein-coupled receptor signaling pathway; positive regulation of cytosolic calcium ion concentration; and positive regulation of protein-containing complex assembly. Predicted to be located in cell surface. Is expressed in several structures, including alimentary system; brain; heart; sensory organ; and skeleton. Used to study congenital hypothyroidism. Human ortholog(s) of this gene implicated in congenital nongoitrous hypothyroidism 7 and hypertension. Orthologous to human TRHR (thyrotropin releasing hormone receptor).

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
