A number of ELISA Kits are available that target histamine receptor H 1, an alias of the protein, histamine receptor H1. The human protein, encoded by the gene HRH1, is a member of the G-protein coupled receptor 1 family. The protein's cellular localization is indicated to be membrane-associated. Additional synonyms or past names for this protein may include: H1-R, H1R, HH1R, hisH1. Homology is conserved in other species, such as Mouse, Rat, Zebrafish, Frog, Chicken.
