TH, the rate‐limiting enzyme in the biosynthesis of catecholamines, including dopamine, norepinephrine, and epinephrine, was used to identify the sympathetic nerves in skin.[34] The over‐activation of TH by Ser40‐phosphorylation is a key marker of SNS hyperactivation.[37] The positive linear correlation between TH and CAMK2G expression in human neuroblastoma cell line suggested that CAMK2γ is closely related to SNS activity. Here, TH is linked to neuroblastoma.
