InnateDB Annotation
Summary
HRH4 is a histamine receptor that can mediate cytokine production (e.g. IL6) from mast cells. HRH4 is also able to synergize with other inflammatory signals, such as LPS, to potentiate cytokine production and contribute to inflammation. (Demonstrated in murine model)

Entrez Gene
Summary Histamine is a ubiquitous messenger molecule released from mast cells, enterochromaffin-like cells, and neurons. Its various actions are mediated by a family of histamine receptors, which are a subset of the G-protein coupled receptor superfamily. This gene encodes a histamine receptor that is predominantly expressed in haematopoietic cells. The protein is thought to play a role in inflammation and allergy reponses. Multiple transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, May 2009]
