Technical Data
Serotonin Receptor 3B (HTR3B, 5-hydroxytryptamine (serotonin) receptor 3B, 5-HT-3B, 5-HT3B, 5-HT-3B, 5-hydroxytryptamine receptor 3B, HTR3B)
Serotonin (5-hydroxytryptamine, 5-HT), originally discovered as a serum factor plays important roles in regulating diverse biological processes in central and peripheral nervous systems, cardiovascular systems, and gastrointestinal systems . The 5-HT3 receptors are distinguished from other 5-HT receptors by their structure and function. 5-HT3 receptors span the membrane only four times and are ligand-gated, cation-selective ion channels that mediate neuronal excitation and exocytotic release of neurotransmitters within the peripheral and central nervous systems. Functional studies done on isolated tissues have revealed heterogeneity of this receptor. The human 5-HT3R-As cDNA contains an open reading frame of 1434 base pairs predicting a 23-residue signal peptide and a mature receptor subunit of 455 amino acids. The human subunit exhibits 85% and 84% amino acid sequence identity to the mouse and rat receptors, respectively. Anti-5-HT3R polyclonal antibody shows immunoreactivity in the forebrain (olfactory regions, hippocampal formation and amygdala), sensory and motor nuclei of brainstem and spinal cord.

Suitable for use in ELISA and Western Blot. Other applications not tested.
