Common Name: HTRB3 Type: Gene
Chromosome: 11 (NC_000011.10) Locus: N/A
HUGO Symbol: HTRB3 Full Name: 5-hydroxytryptamine receptor 3B
Exons: 9 Introns: 8

This gene encodes one of the several receptors for 5-hydroxytryptamine (serotonin). It is a 5-HT3 (5-hydroxytryptamine type 3) receptor, member of the Cys-loop family of transmitter-gated ion channels. The 5-HT3 receptor is a pentamer of subunits that assemble to form a central ion channel. It causes fast, depolarizing responses in neurons after activation. It is mainly functional as a heteropentameric complex with subunit A (HTR3A). Genetic variance in HTRB3 gene associated with acute chest syndrome (ACS) in patients with sickle cell disease. ACS is a form of acute lung injury caused by vaso-occlusion within the pulmonary microvasculature. Etiologies either trigger vaso-occlusion (e.g., infection, asthma, hypoventilation) or are a result of vaso-occlusion (e.g., bone marrow and fat emboli).

Synonyms: 5-HT3B
