Updated project metadata. This submission contains human protein interaction datasets of four proteins (BCL2, TDP-43, MDM2, PTEN) across three cancer cell lines (G401, T47D, A375) and one iPSC-derived neuronal cell line (glutamatergic patterned induced neuron, GPiN). The data were generated to demonstrate the utility of Genoppi (lagelab.org/genoppi), an open-source computational tool that enables integration of quantitative proteomic results with genetic data. Our analyses show a general pattern of both cell-type-independent and cell-type-specific interactions for the tested proteins. In particular, our results suggest that the neuron-specific interactions of BCL2 and TDP-43 are mediating their genetic involvement in amyotrophic lateral sclerosis.
