Uniprot ID
CYB5_HUMAN
Interaction Name CYB5A, POR and CYP1A2 heterooligomerization [1]
Studied Cell Lines Whole-BTC cell line
Activity Km = 0.6 microM
Description Cytochrome b5 (CYB5A) and NADPH-CYP450 reductase (POR) are reported to heterooligomerize with the CYP1A2 gene, which is necessary for sustaining the enzyme activity of Cytochrome P450 1A2. As a result, the interaction among CYB5A, POR and CYP1A2 is necessary for sustaining the drug-metabolizing process of Cytochrome P450 1A2.
                            Cytochrome P450 2E1 (CYP2E1) Health Heterooligomer
Uniprot ID
CP2E1_HUMAN
Interaction Name CYP2E1-CYP1A2 heterooligomerization [2]
Studied Cell Lines Escherichia coli cell line
Affected Substrate(s): 7-Ethoxyresorufin (Metabolic product: Dealkylation of 7-ethoxyresorufin)
Description Cytochrome P450 2E1 (CYP2E1) is reported to heterooligomerize with the CYP1A2 protein, which leads to an increased activity of the drug-metabolizing enzyme Cytochrome P450 1A2. As a result, the interaction between CYP2E1 and CYP1A2 can facilitate the drug-metabolizing process of Cytochrome P450 1A2.
                            NADPH-CYP450 reductase (POR) Health Heterooligomer
Uniprot ID
NCPR_HUMAN
Interaction Name POR, CYB5A and CYP1A2 heterooligomerization [1]
Studied Cell Lines Whole-BTC cell line
Activity Km = 0.6 microM
Description NADPH-CYP450 reductase (POR) and Cytochrome b5 (CYB5A) are reported to heterooligomerize with the CYP1A2 gene, which is necessary for sustaining the enzyme activity of Cytochrome P450 1A2. As a result, the interaction among POR, CYB5A and CYP1A2 is necessary for sustaining the drug-metabolizing process of Cytochrome P450 1A2.

HDAC1_HUMAN
Interaction Name HDACs-CYP1A2 interaction [3]
Studied Cell Lines HeLa cell line
Description Histone deacetylases (HDACs) are reported to deacetylate the CYP1A2 gene and thereby repress the transcriptional activity of the drug-metabolizing enzyme Cytochrome P450 1A2. As a result, the interaction between HDACs and CYP1A2 can inhibit the drug-metabolizing process of Cytochrome P450 1A2.

Uniprot ID
DNMT1_HUMAN
Interaction Name DNMT-CYP1A2 interaction [4]
Studied Cell Lines Placental villi
Description DNA methyltransferase (DNMT) is reported to significantly hyper-methylate the CYP1A2 gene, which leads to a significantly decreased expression of the drug-metabolizing enzyme Cytochrome P450 1A2. As a result, the interaction between DNMT and CYP1A2 can significantly affect the drug-metabolizing process of Cytochrome P450 1A2.
