Abstract

Abstract: Objective To identify the specific protein interactions involved in Bat3-mediated apoptosis.Methods Tandem affinity purification(TAP)was utilized to investigate Bat3-protein interactions,during which full-length human Bat3 fused with Strep2 and FLAG tag as a bait was used to screen the specific protein-protein interactions.The isolated proteins were identified with mass spectrometry.Results TAP studies showed that Ubl4A was identified as a Bat3-binding partner.Further investigation using co-immunoprecipitation confirmed that Bat3 was associated with Ubl4A.Conclusion TAP was successfully established and is suitable for isolating the binding partners of Bat3.

Key words: Bat3, apoptosis, tandem affinity purification
