Description : Histamine N-methyltransferase (HNMT) is found in the cytosol and uses S-adenosyl-L-methionine as the methyl donor. HNMT inactivates histamine by N-methylation. Histamine is involved in regulation and modulation of immune response through the stimulation of four distinct subtypes of receptors, H1, H2, H3, and H4, present on the target cells. Histamine is inactivated by the histamine-metabolizing enzyme histamine N-methyltransferase (HNMT) in bronchus, kidney, and the central nervous system. It plays an important role in degrading histamine and in regulating the airway response to histamine.

Upon incubation of HEK-RXFP1 with recombinant His-tagged CTRP8 (Creative BioMart), HAtargeted co-IP and Western blot analysis revealed the successful pull down of both HA-RXFP1 and CTRP8-His (Fig. 12).. Similar results were obtained when HEK293T-RXFP1-HA transfectants were transiently transfected with a construct encoding human FLAG-tagged CTRP8 followed by HA-targeted immunoprecipitation and Western blot detection of HA and FLAG epitopes (data not shown).Similar results were obtained when HEK293T-RXFP1-HA transfectants were transiently transfected with a construct encoding human FLAG-tagged CTRP8 followed by HA-targeted immunoprecipitation and Western blot detection of HA and FLAG epitopes (data not shown).
