PDE10A

cAMP and cAMP-inhibited cGMP 3',5'-cyclic phosphodiesterase 10A UniProt accession Q9Y233

Plays a role in signal transduction by regulating the intracellular concentration of cyclic nucleotides (PubMed:10373451, PubMed:10393245, PubMed:16330539, PubMed:17389385, PubMed:27058447). Can hydrolyze both cAMP and cGMP, but has higher affinity for cAMP and is more efficient with cAMP as substrate (PubMed:10373451, PubMed:10393245, PubMed:17389385, PubMed:27058447). May play a critical role in regulating cAMP and cGMP levels in the striatum, a region of the brain that contributes to the control of movement and cognition (PubMed:27058447)

Abundant in the putamen and caudate nucleus regions of brain and testis, moderately expressed in the thyroid gland, pituitary gland, thalamus and cerebellum

Source: UniProt

The tandem GAF domains bind cAMP, and regulate enzyme activity. The binding of cAMP stimulates enzyme activity

Composed of a C-terminal catalytic domain containing two divalent metal sites and an N-terminal regulatory domain which contains one cyclic nucleotide-binding region

  • Dyskinesia, limb and orofacial, infantile-onset (IOLOD)

    An autosomal recessive, early-onset hyperkinetic movement disorder characterized by axial hypotonia, dyskinesia of the limbs and trunk, orofacial dyskinesia, drooling, and dysarthria. The severity of the hyperkinesis is variable.

  • Striatal degeneration, autosomal dominant 2 (ADSD2)

    An autosomal dominant disorder characterized by striatal degeneration and dysfunction of basal ganglia, resulting in hyperkinesis.
