Entrez ID 51816
Gene name Adenosine deaminase 2
Gene symbol ADA2
Synonyms (NCBI Gene)
ADGFCECR1IDGFLPANSNEDSVAIHS
Chromosome 22
Chromosome location 22q11.1
Summary This gene encodes a member of a subfamily of the adenosine deaminase protein family. The encoded protein is one of two adenosine deaminases found in humans, which regulate levels of the signaling molecule, adenosine. The encoded protein is secreted from m
