Tyrosine hydroxylase is an enzyme that controls the rate-limiting step in making catecholamines. In the supplied source, its protein levels and activity-related phosphorylation are described as being regulated in the short term by the ubiquitin-proteasome system, with impaired proteasome activity linked to higher tyrosine hydroxylase levels in hypertension-related neurons.
