CYP1A2

シトクロムP450 1A2は、略称CYP1A2と呼ばれ、シトクロムP450混合機能オキシダーゼのメンバーのひとつであり、人体において生体異物の代謝に関与している。 CYP1A2の発現は、様々な栄養成分によって誘導されるとみなされている。 CYP1A2の選択的な基質、誘導剤及び阻害剤の一覧を以下の表に示す。 様々な薬剤や食品との薬物相互作用があり、薬の作用が強まったり弱まったりする事が報告されている。例えば喫煙は CYP1A2 で代謝される薬の作用を弱める。 ^ a b c GRCh38: Ensembl release 89: ENSG00000140505 - Ensembl, May 2017 ^ a b c GRCm38: Ensembl release 89: ENSMUSG00000032310 - Ensembl, May 2017 ^ Human PubMed Reference: ^ Mouse PubMed Reference: ^ Fontana R, Lown K, Paine M, Fortlage L, Santella R, Felton J, Knize M, Greenberg A, Watkins P (1999). “Effects of a chargrilled meat diet on expression of CYP3A, CYP1A, and P-glycoprotein levels in healthy volunteers”.
