Uniprot ID
HDAC1_HUMAN
Interaction Name HDACs-TPH2 interaction [1]
Studied Cell Lines RN46A cells
Description Histone deacetylases (HDACs) are reported to deacetylate the TPH2 gene and thereby repress the transcriptional activity of the drug-metabolizing enzyme Tryptophan 5-hydroxylase 2. As a result, the interaction between HDACs and TPH2 can inhibit the drug-metabolizing process of Tryptophan 5-hydroxylase 2.

REST_HUMAN
Interaction Name REST-TPH2 interaction [2]
Studied Cell Lines C6-glioma cell line
Ensembl ID
ENSG00000084093
Description X2 box repressor (REST) is reported to activate the transcription of TPH2 gene, which leads to an increased expression of the drug-metabolizing enzyme Tryptophan 5-hydroxylase 2. As a result, the interaction between REST and TPH2 can activate the drug-metabolizing process of Tryptophan 5-hydroxylase 2.
