Summary: Predicted to enable beta2-adrenergic receptor activity and norepinephrine binding activity. Acts upstream of or within pigmentation and regulation of heart rate. Predicted to be located in membrane. Predicted to be active in plasma membrane. Is expressed in several structures, including blood; digestive system; musculature system; nervous system; and pleuroperitoneal region. Human ortholog(s) of this gene implicated in several diseases, including autoimmune disease (multiple); disease of metabolism (multiple); kidney failure (multiple); lung disease (multiple); and open-angle glaucoma (multiple). Orthologous to human ADRB2 (adrenoceptor beta 2). [provided by Alliance of Genome Resources, Apr 2025]

These data collectively reveal the potential of beta2ARag to improve skin scarring.
Title: β2-adrenoceptor activation modulates skin wound healing processes to reduce scarring.
Zebrafish larvae lacking beta1AR expression by morpholino knockdown displayed lower heart rates than control fish, whereas larvae deficient in both beta2aAR and beta2bAR expression exhibited significantly higher heart rates than controls.

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.
