Tagging a protein with TurboID allows studying protein interactions in different types of cells and organs and developmental stages. This is a suitable tool for proximity labelling experiments as described in Mair et al. (2019). Proximity labelling of protein complexes and cell-type-specific organellar proteomes in Arabidopsis enabled by TurboID. Elife . 2019 Sep 19;8:e47864. doi: 10.7554/eLife.47864. This tag has MW of 35 kDa.
Recombinant mutated BirA protein from E.coli produced using the following plasmid: TurboID-His6_pET21a, (Plasmid #107177). Expression was done in a vector that allowed for the generation of an untagged protein (without HIS6tag).
