Insights into the cellular role of Serine19 phosphorylation in tyrosine hydroxylase
K C, Kunwar Jung (Master thesis, 2016-06-01)Tyrosine hydroxylase (TH) is the rate limiting enzyme that catalyzes the first step in the biosynthesis of catecholamines. The posttranslational modification of its regulatory domain controls the regulation of TH enzyme ... -
The Pah-R261Q mouse reveals oxidative stress associated with amyloid-like hepatic aggregation of mutant phenylalanine hydroxylase
Aubi Catevilla, Oscar; Prestegård, Karina Skjervheim; K C, Kunwar Jung; Shi, Tie-Jun; Ying, Ming; Grindheim, Ann Kari; Scherer, Tanja; Ulvik, Arve; McCann, Adrian; Spriet, Endy; Thöny, Beat; Martinez, Aurora (Journal article; Peer reviewed, 2021)Phenylketonuria (PKU) is caused by autosomal recessive variants in phenylalanine hydroxylase (PAH), leading to systemic accumulation of L-phenylalanine (L-Phe) that may reach neurotoxic levels. A homozygous Pah-R261Q mouse, ... -
Phosphorylation at serine 31 targets tyrosine hydroxylase tovesicles for transport along microtubules
Jorge Finnigan, Ana; Kleppe, Rune; K C, Kunwar Jung; Ying, Ming; Marie, Michael Bruno Eric; Rios Mondragon, Ivan; Salvatore, Michael F; Saraste, Jaakko; Martinez, Aurora (Peer reviewed; Journal article, 2017)Tyrosine hydroxylase (TH) catalyzes the conversion of L-tyrosine into L-DOPA, which is the rate-limiting step in the synthesis of catecholamines, such as dopamine, in dopaminergergic neurons. Low dopamine levels and death ... -
Regulatory post-translational modifications and protein-protein interactions involved in function and proteostasis of aromatic amino acid hydroxylases
K C, Kunwar Jung (Doctoral thesis, 2021-09-16)The non-heme iron and (6R)-L-erythro-5,6,7,8-tetrahydrobiopterin (BH4) dependent aromatic amino acid hydroxylases (AAAHs) family of enzymes include phenylalanine hydroxylase (PAH), tyrosine hydroxylase (TH), and tryptophan ...
