                            Cytochrome b5 (CYB5A) Health Heterooligomer
Uniprot ID
CYB5_HUMAN
Interaction Name CYB5A-CYP3A5 heterooligomerization [1], [2]
Studied Cell Lines DLPC vesicles
Description Cytochrome b5 (CYB5A) is reported to heterooligomerize with the CYP3A5 protein, which leads to an increased activity of the drug-metabolizing enzyme Cytochrome P450 3A5. As a result, the interaction between CYB5A and CYP3A5 can facilitate the drug-metabolizing process of Cytochrome P450 3A5.
                            Cytochrome P450 2E1 (CYP2E1) Health Heterooligomer
Uniprot ID
CP2E1_HUMAN
Interaction Name CYP2E1-CYP3A5 heterooligomerization [3]
Studied Cell Lines Insect cell microsomes
Affected Substrate(s): 7-Benzyloxyquinoline (Metabolic product: 7-BQ O-debenzylation)
Description Cytochrome P450 2E1 (CYP2E1) is reported to heterooligomerize with the CYP3A5 protein, which leads to a slight effect on the activity of drug-metabolizing enzyme Cytochrome P450 3A5. As a result, the interaction between CYP2E1 and CYP3A5 slightly affects the drug-metabolizing process of Cytochrome P450 3A5.
                            Mutated NADPH-CYP450 reductase (mPOR) Health Heterooligomer
Uniprot ID
NCPR_HUMAN
Interaction Name mPOR-CYP3A5 heterooligomerization [4], [5]
Studied Cell Lines Escherichia coli BL21(DE3) cell line
Affected Substrate(s): Tacrolimus
Description Mutated NADPH-CYP450 reductase (mPOR) is reported to heterooligomerize with the CYP3A5 protein, which leads to a suppressed activity of the drug-metabolizing enzyme Cytochrome P450 3A5. As a result, the interaction mutant type between mPOR and CYP3A5 can inhibit the drug-metabolizing process of Cytochrome P450 3A5.
                            NADPH-CYP450 reductase (POR) Health Heterooligomer
Uniprot ID
NCPR_HUMAN
Interaction Name POR-CYP3A5 heterooligomerization [4], [5]
Studied Cell Lines Reconstituted liposomes
Affected Substrate(s): Tacrolimus
Description NADPH-CYP450 reductase (POR) is reported to heterooligomerize with the CYP3A5 protein, which leads to activation of the drug-metabolizing enzyme Cytochrome P450 3A5. As a result, the interaction between POR and CYP3A5 can activate the drug-metabolizing process of Cytochrome P450 3A5.

Uniprot ID
DNMT1_HUMAN
Interaction Name DNMT-CYP3A5 interaction [6]
Studied Cell Lines Live tissue
Description DNA methyltransferase (DNMT) is reported to significantly hyper-methylate the CYP3A5 gene, which leads to a significantly decreased expression of the drug-metabolizing enzyme Cytochrome P450 3A5. As a result, the interaction between DNMT and CYP3A5 can significantly affect the drug-metabolizing process of Cytochrome P450 3A5.
