Part:BBa_K3168003

SmallBitNanoLuc

This basic part codes for the small bit of NanoLuc, which can be used as a split reporter. In combination with the large bit of NanoLuc and the addition of furimazine (the substrate), bright blue light is emitted (figure 1). A flexible (GGS)₅ linker is located in front of the small bit to enable the formation of fusion proteins. A strep-tag is also included at the end for protein purification. There are different variants of the NanoLuc small bit with different affinities for the large bit (Dixon, 2015). This basic part has a relatively low affinity (2.5*10^-6M) to prevent high background signals when combined with NanoLuc large bit. The affinity can be tuned by incorporating certain mutations (Dixon, 2015).

Usage and Biology

Split reporters have been used a lot to detect protein-protein interactions and for screening purposes (Dixon, 2015). NanoLuc is a small, structurally robust and very bright luciferase. Many methods have been developed using the split variant of NanoLuc, such as the HiBiT technology and NanoLuc ternary technology (Ohmuro-Matsuyama, 2019).
