Gene: ADA2 (adenosine deaminase 2) Homo sapiens
Symbol: ADA2
Name: adenosine deaminase 2
Description: Exhibits several functions, including adenosine deaminase activity; protein homodimerization activity; and zinc ion binding activity. Involved in adenosine catabolic process. Localizes to extracellular space. Implicated in Sneddon syndrome.
Type: protein-coding
RefSeq Status: REVIEWED
Also known as: adenosine deaminase CECR1; ADGF; cat eye syndrome chromosome region, candidate 1; cat eye syndrome critical region protein 1; CECR1; IDGFL; PAN; SNEDS; VAIHS
