Summary: Enables D1 dopamine receptor binding activity. Involved in adenylate cyclase-activating dopamine receptor signaling pathway. Acts upstream of or within response to lipopolysaccharide. Predicted to be active in plasma membrane. Is expressed in several structures, including alimentary system; brain; genitourinary system; immune system; and integumental system. Orthologous to human PTGER1 (prostaglandin E receptor 1). [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.
