Extended Data Fig. 2. The sequences of GRABDA sensors and the residues related to affinity-tuning, cpRFP and cpEGFP optimization.
a,b, The sequences of rGRABDA1m (a) and GRABDA2m (b). The residues related to affinity-tuning, cpRFP (a) and cpEGFP (b) optimization are marked. T2055.54M was introduced to rDA1m and DA2m to generate rDA1h and DA2h, respectively.
