PDE10A

Various cellular responses are regulated by the second messengers cAMP and cGMP. Phosphodiesterases, such as PDE10A, eliminate cAMP- and cGMP-mediated intracellular signaling by hydrolyzing the cyclic nucleotide to the corresponding nucleoside 5-prime monophosphate (Fujishige et al., 2000 [PubMed 10998054]).[supplied by OMIM

phosphodiesterase 10A

Plays a role in signal transduction by regulating the intracellular concentration of cyclic nucleotides (PubMed:10373451, PubMed:10393245, PubMed:16330539, PubMed:27058447, PubMed:17389385).
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:27058447, PubMed:17389385).
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).

Cytoplasm, cytosol

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.
