For regulators of apoptosis (43), so we first tested the samples for the presence of Bcl-2 family mRNA transcripts reported to associate with KHDRBS1 (43). We purified Halo-TNIP2 196 ?429 in the presence of RNase inhibitors, and analyzed RNA extracted from the affinity purified samples by reverse transcription followed by PCRMolecular Cellular Proteomics 15.Mapping Interactions for the TNIP2 Hub
