BioID-proximity labeling of GATAD1 variants

To gain insights into the interactome of wild-type (WT) and S102P mutant GATAD1, we utilized the BioID method, which enables the study of protein-protein interactions. Specifically, we performed BioID proximity labeling experiments in stable Flp-In cells expressing different GATAD1 variants fused to BirA*_FLAG. These variants included BirA*_FLAG_GATAD1-WT, BirA*_FLAG_GATAD1-S102P, BirA*_FLAG_GATAD1-S102D, and BirA*_FLAG_GATAD1-S102A. By employing this approach, we aimed to characterize the protein interactors associated with these GATAD1 variants and gain insights into the functional consequences of the S102P mutation.
