Gene type: protein coding
RefSeq status: VALIDATED
Organism: Mus musculus
Lineage: Eukaryota; Metazoa; Chordata; Craniata; Vertebrata; Euteleostomi; Mammalia; Eutheria; Euarchontoglires; Glires; Rodentia; Myomorpha; Muroidea; Muridae; Murinae; Mus; Mus
Also known as: H2R; HH2R
Summary: Predicted to enable heterocyclic compound binding activity; histamine receptor activity; and neurotransmitter receptor activity. Acts upstream of or within several processes, including epithelial cell morphogenesis; gastric acid secretion; and learning or memory. Predicted to be active in dendrite and plasma membrane. Is expressed in brain; early conceptus; stomach; and uterus. Orthologous to human HRH2 (histamine receptor H2). [provided by Alliance of Genome Resources, Dec 2024]
Expression: Broad expression in frontal lobe adult (RPKM 1.9), stomach adult (RPKM 1.8) and 18 other tissues See more

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.
