RGD ID: 61800
Description: 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; postsynaptic membrane; and 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); PARTICIPATES IN calcium/calcium-mediated signaling pathway; INTERACTS WITH (R,R)-tramadol; (S)-nicotine; 1-bromopropane.
Type: protein-coding
