Adenosine deaminase (ADA)
Adenosine deaminase is an enzyme that breaks down adenosine and deoxyadenosine; blocking it with pentostatin poisons lymphocytes, which is why the drug works in hairy cell leukaemia and some T-cell cancers. This dossier gathers the 1 product (1 approved), 0 trials, 0 pathways and 0 resistance routes in the corpus that involve it, with external identifiers so it can be joined to UniProt, ChEMBL, Open Targets and the rest of biology.
Biology
ADA is a zinc-dependent hydrolase expressed in most tissues and at high levels in lymphoid cells. Inhibiting it raises intracellular deoxyadenosine triphosphate, which blocks ribonucleotide reductase and DNA synthesis and triggers apoptosis, an effect most marked in lymphocytes with high deoxynucleoside kinase activity. Pentostatin binds the enzyme almost irreversibly; cladribine, the other purine analogue used in hairy cell leukaemia, is instead a substrate-resistant deoxyadenosine analogue.
- Lymphocytes and lymphoid tissue (high)
- Widely expressed in other tissues at lower levels
- Also present in plasma as extracellular ADA
