About Htr2a

Primary_assembly 15: 49,950,804-50,020,928 forward strand.mRatBN7.2:CM026988.1

This gene has 1 transcript (splice variant), 222 orthologues, 8 paralogues and is associated with 36 phenotypes. Biased expression in Brain (RPKM 49.5), Heart (RPKM 14.5) and 6 other tissues.

Summary

Predicted to enable several functions, including 1-(4-iodo-2,5-dimethoxyphenyl)propan-2-amine binding activity; Gq/11-coupled serotonin receptor activity; and serotonin binding activity. Involved in several processes, including blood vessel diameter maintenance; detection of stimulus involved in sensory perception of pain; and modulation of chemical synaptic transmission. Located in several cellular components, including cell body fiber; dendritic shaft; and neuronal cell body. Is active in glutamatergic synapse. Is integral component of postsynaptic membrane and integral component of presynaptic membrane. Used to study congestive heart failure; hyperglycemia; and pancreatitis. Biomarker of bladder neck obstruction and schizophrenia. Human ortholog(s) of this gene implicated in several diseases, including alcohol use disorder; anorexia nervosa; major depressive disorder; obesity; and obsessive-compulsive disorder. Orthologous to human HTR2A (5-hydroxytryptamine receptor 2A). [provided by Alliance of Genome Resources, Apr 2022]
