cAMP-mediated stimulation of tyrosine hydroxylase mRNA translation is mediated by polypyrimidine-rich sequences within its 3'-untranslated region and poly(C)-binding protein 2.

Abstract excerpt

Tyrosine hydroxylase (TH) plays a critical role in maintaining the appropriate concentrations of catecholamine neurotransmitters in brain and periphery, particularly during long-term stress, long-term drug treatment, or neurodegenerative diseases. Its expression is controlled by both transcriptional and post-transcriptional mechanisms. In a previous report, we showed that treatment of rat midbrain slice explant...
