GBD-Domain

The GBD domain and its ligand (BBa_K771106) are suitable tools for protein colocalizaion. Initially, the domain was a part of the N-WASP protein (GTPase binding domain) in Rattus rattus. The GBD domain is used as a binding unit of the so-called protein scaffold published by Dueber et al. in 2012. The scaffold (BBa_K1497033) is composed of different binding units, which enable the assembly of multiple target proteins. This BioBrick adds a BglII and BamHI restriction site in front of and behind the previously constructed domain sequence (BBa_K771105). Now, different binding units of the scaffold protein can be fused together without the introduction of restriction sites. This allows the easy construction of BioBricks of different permutations of the scaffold protein domains.

Figure 1 Crystal structure of the GBD domain from the N-WASP protein (red) of Rattus rattus binding the small molecule Wiskostatin (1-(3,6-Dibromo-carbazol-9-yl)-3-dimethylamino-propan-2-ol). The GBD domain is locked by Wiskostatin in its autoinhibited binding conformation (Peterson et al. 2004). PDB entry 1T84.
