Measure Target Engagement to PRMT5 in Live Cells
Protein arginine methyltransferase 5 (PRMT5) catalyzes arginine methylation for both histone and non-histone substrates and uses S-adenosylmethionine (SAM) as the cofactor and methyl group donor. PRMT5 regulates a wide spectrum of cellular processes, such as cell signaling and differentiation, RNA splicing and DNA damage response, and has been shown to be a promising synthetic lethality target for MTAP (methylthioadenosine phosphorylase)-deleted cancer cells.
The NanoBRET® TE PRMT5 Assay can be used to quantify affinity of PRMT5 inhibitors with different modes of action in live cells. The assay is based on the NanoBRET® technology, an energy transfer technique designed to measure molecular proximity in living cells.

アッセイ原理
NanoBRET™ TargetEngagement(TE)アッセイは、生物発光共鳴エネルギー移動(BRET)を介して、標的タンパク質に対する試験化合物の親和性を生細胞で測定することを可能にします。このアッセイでは、細胞内で発現した NanoLuc®ルシフェラーゼ-標的タンパク質融合体から、標的タンパク質に結合する細胞透過性蛍光NanoBRET™トレーサーへの発光エネルギーの伝達が起こります。NanoBRET™ TE E3 リガーゼアッセイでは、NanoLuc®-E3リガーゼ融合タンパク質を哺乳動物細胞で発現させます。BRETシグナルを生成するために、固定濃度の細胞透過性蛍光 NanoBRET™ TE トレーサーを細胞に添加すると、NanoLuc®-E3リガーゼ融合タンパク質に結合します。次に E3リガーゼに結合する化合物を添加すると、NanoBRET™シグナルが用量依存的に減少します。このデータは、生細胞での標的 E3 リガーゼタンパク質に対する分解誘導化合物の細胞内親和性を示しています。
Evaluate Target Engagement at Substrate and Cofactor Binding Pockets
NanoBRET™ TE E3 Ligase Assay は、分解誘導化合物の細胞内での利用可能性を測定するためにも使用できます。細胞内の可用性を測定するために、NanoBRET™ TE E3 Ligase Assay の簡単なワークフローを実行します。これには、生細胞モードと透過処理細胞モードの2つのモードが含まれます。生細胞モードで行われる NanoBRET™TE E3 Ligase Assay の場合、細胞膜など化合物の透過や結合性に影響を与える因子が存在する生細胞内で親和性を測定します。一方、透過処理細胞モードでは、NanoBRET™ TE E3 Ligase Assay を、細胞膜がない状態でE3リガーゼに対する化合物の固有の親和性を定量化します。次に、両方のモードからの親和性データを使用して、対照化合物と比較した化合物の細胞内利用可能性を計算します。
A
Measure Compound Binding to PRMT5-MTA Complex
In MTAP-deficient cancer cells, there is an accumulation of 5′-Methylthioadenosine (MTA), an intermediate in the methionine salvage pathway. An elevated level of MTA leads to inhibition of PRMT5, sensitizing the cancer cells to further loss of PRMT5 activity and exposing a vulnerability in MTAP-deficient cancers. Developing inhibitors that preferentially engage the PRMT5-MTA complex can exploit this synthetic lethal interaction to selectively target MTAP-deficient cancer cells. The NanoBRET® TE PRMT5 Assay can be used to assess target binding by MTA-cooperative PRMT5 inhibitors in live cells.
See the PRMT5 TE Assay Scientific Poster on how the assay can be used to evaluate the impact of MTA on inhibitor-PRMT5 interactions and characterize MTA-cooperative inhibitors.
