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. Acts upstream of or within positive regulation of fat cell differentiation; positive regulation of phosphorylation; and protein localization to cytoskeleton. Predicted to be located in several cellular components, including cell body fiber; dendritic shaft; and neuronal cell body. Predicted to be part of G protein-coupled serotonin receptor complex. Predicted to be active in dendrite. Predicted to be integral component of plasma membrane. Is expressed in several structures, including alimentary system; central nervous system; genitourinary system; heart; and sensory organ. 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]

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
