ADORA2B
geneOn this page
Summary
ADORA2B (adenosine A2b receptor, HGNC:264) is a protein-coding gene on chromosome 17p12, encoding Adenosine receptor A2b (P29275). Receptor for adenosine.
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.
