Lineage: Eukaryota; Metazoa; Chordata; Craniata; Vertebrata; Euteleostomi; Mammalia; Eutheria; Euarchontoglires; Glires; Rodentia; Myomorpha; Muroidea; Muridae; Murinae; Mus; Mus
Also known as: IP; PGI2
Summary: Predicted to enable prostacyclin receptor activity. Involved in adenylate cyclase-activating G protein-coupled receptor signaling pathway; negative regulation of platelet-derived growth factor receptor signaling pathway; and negative regulation of smooth muscle cell proliferation. Acts upstream of or within response to lipopolysaccharide. Predicted to be located in cytosol. Predicted to be active in plasma membrane. Is expressed in several structures, including alimentary system; gallbladder; genitourinary system; hemolymphoid system gland; and limb segment. Orthologous to human PTGIR (prostaglandin I2 receptor). [provided by Alliance of Genome Resources, Dec 2024]

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.
