CC -!- FUNCTION: The H3 subclass of histamine receptors could mediate the
CC histamine signals in CNS and peripheral nervous system. Signals through
CC the inhibition of adenylate cyclase and displays high constitutive
CC activity (spontaneous activity in the absence of agonist). Agonist
CC stimulation of isoform 3 neither modified adenylate cyclase activity
CC nor induced intracellular calcium mobilization.
CC -!- SUBCELLULAR LOCATION: Cell membrane; Multi-pass membrane protein.
CC -!- ALTERNATIVE PRODUCTS:
CC Event=Alternative splicing; Named isoforms=7;
CC Comment=Additional isoforms seem to exist.;

CC IsoId=Q9Y5N1-6; Sequence=VSP_001883;
CC Name=7;
CC IsoId=Q9Y5N1-7; Sequence=VSP_001884;
CC -!- TISSUE SPECIFICITY: Expressed predominantly in the CNS, with the
CC greatest expression in the thalamus and caudate nucleus. The various
CC isoforms are mainly coexpressed in brain, but their relative expression
CC level varies in a region-specific manner. Isoform 3 and isoform 7 are
CC highly expressed in the thalamus, caudate nucleus and cerebellum while
CC isoform 5 and isoform 6 show a poor expression. Isoform 5 and isoform 6
CC show a high expression in the amygdala, substantia nigra, cerebral
CC cortex and hypothalamus. Isoform 7 is not found in hypothalamus or
CC substantia nigra.
CC -!- MISCELLANEOUS: Does not bind to cimetidine and tripolidine. Shows
CC modest affinity for thioperamide, imetit, N-alpha-methylhistamine and
CC R(-)-alpha-methylhistamine. Isoform 4 is unable to bind to iodoproxyfan
CC while isoforms 1 and 3 bind it with high affinity.
CC -!- SIMILARITY: Belongs to the G-protein coupled receptor 1 family.
