Summaries for ADORA2B Gene

Entrez Gene Summary for ADORA2B Gene

  • This gene encodes an adenosine receptor that is a member of the G protein-coupled receptor superfamily. This integral membrane protein stimulates adenylate cyclase activity in the presence of adenosine. This protein also interacts with netrin-1, which is involved in axon elongation. The gene is located near the Smith-Magenis syndrome region on chromosome 17. [provided by RefSeq, Jul 2008]

GeneCards Summary for ADORA2B Gene

ADORA2B (Adenosine A2b Receptor) is a Protein Coding gene. Among its related pathways are Signaling by GPCR and Surfactant metabolism. GO annotations related to this gene include G-protein coupled receptor activity and G-protein coupled adenosine receptor activity. An important paralog of this gene is ADORA2A.

UniProtKB/Swiss-Prot for ADORA2B Gene

  • Receptor for adenosine. The activity of this receptor is mediated by G proteins which activate adenylyl cyclase.

Tocris Summary for ADORA2B Gene

  • Adenosine A2B receptors are members of the adenosine receptor group of G-protein-coupled receptors that also includes A1, A2A and A3. A2B receptors display high expression levels in the cecum, colon and bladder, with lower levels in the lung, blood vessels and eye.
