Protein Structure

UniProt Annotation

Function

The H4 subclass of histamine receptors could mediate the histamine signals in peripheral tissues. Displays a significant level of constitutive activity (spontaneous activity in the absence of agonist). {ECO:0000269PubMed:12503632}.

Subcellular Localization

Cell membrane; Multi-pass membrane protein.

Disease Associations

Tissue Specificity

Expressed primarily in the bone marrow and eosinophils. Shows preferential distribution in cells of immunological relevance such as T-cells, dendritic cells, monocytes, mast cells, neutrophils. Also expressed in a wide variety of peripheral tissues, including the heart, kidney, liver, lung, pancreas, skeletal muscle, prostate, small intestine, spleen, testis, colon, fetal liver and lymph node. {ECO:0000269PubMed:12503632}.
