    text
  • cAMP signaling in the Golgi area and the cytosol in neurons is controlled through alteration of subcellular localization of PDE10A brought by activation of PKA in response to intracellular elevations of cAMP
  • most often associated with membranes in dendrites and spines
  • basic FUNCTION
  • exhibiting unique kinetic properties and inhibitor sensitivity
  • playing a role in signal transduction by regulating the intracellular concentration of cyclic nucleotides
  • may have a role in the pain pathway of migraine as well as trigeminal neuralgia and trigeminal autonomic cephalalgias
  • potential role of PDE10A in the adaptation of cyclic nucleotide signaling to daily changes in light intensity in retinal neurons including photoreceptors
  • is potently stimulated by cAMP, and the GAF-mediated stimulation alters the enzymatic parameters such that the enzyme acts as a cAMP-specific phosphodiesterase
  • plays a pivotal role in striatal signaling and striatum-mediated salience attribution
  • critical role of PDE10A in motor control
  • contributes to the regulation of the intracellular levels of cyclic adenosine monophosphate (cAMP) and cyclic guanosine monophosphate (cGMP)

    REGULATION
    activated by cAMP, is the only PDE activated by cAMP
    inhibited by by the non-specific PDE inhibitor, IBMX
    by cGMP
    Other phosphorylation of PDE10A has an impact on the interaction with other signaling proteins and adds an additional line of complexity to the role of PDE10A in regulation of synaptic transmission
