Gene: Htr2b (5-hydroxytryptamine receptor 2B) Rattus norvegicus
Symbol: Htr2b
Name: 5-hydroxytryptamine receptor 2B
RGD ID: 61801
Description: Enables serotonin binding activity. Involved in several processes, including cellular response to organonitrogen compound; hepatic stellate cell activation; and inositol phosphate metabolic process. Located in dendrite; neuronal cell body; and plasma membrane. Used to study heart valve disease. Biomarker of brain infarction and congestive heart failure. Human ortholog(s) of this gene implicated in metabolic dysfunction-associated steatohepatitis and steatotic liver disease. Orthologous to human HTR2B (5-hydroxytryptamine receptor 2B); PARTICIPATES IN calcium/calcium-mediated signaling pathway; INTERACTS WITH (R)-noradrenaline; 2,3,7,8-tetrachlorodibenzodioxine; 3,3',4,4',5-pentachlorobiphenyl.
Type: protein-coding
RefSeq Status: VALIDATED
Previously known as: 5-HT-2B; 5-HT-2F; 5-HT2B; 5-hydroxytryptamine (serotonin) receptor 2B; 5-hydroxytryptamine (serotonin) receptor 2B, G protein-coupled; serotonin receptor 2B; stomach fundus serotonin receptor
