General annotation (Comments)

Function

In the nervous system, could hydrolyze ATP and other nucleotides to regulate purinergic neurotransmission. Could also be implicated in the prevention of platelet aggregation by hydrolyzing platelet-activating ADP to AMP. Hydrolyzes ATP and ADP equally well.

Catalytic activity

A nucleoside 5'-triphosphate + 2 H2O = a nucleoside 5'-phosphate + 2 phosphate.

Cofactor

Ca2+ or Mg2+ By similarity.

Subunit structure

Homodimer; disulfide-linked By similarity.

Subcellular location

Membrane; Multi-pass membrane protein Potential.

Tissue specificity

Highest expression found in vascular endothelium, smooth muscle, spleen and lung.

Post-translational modification

Cleaved into two polypeptides that seem to stay together by noncovalent interactions.

Sequence similarities

Belongs to the GDA1/CD39 NTPase family.
