TAZ (WWTR1) Interactome Analysis using a GBP nanotrap based affinity purification approach


ABSTRACT: The transcriptional co-activator TAZ (WWTR1) plays a crucial role in regulating gene expression related to cell proliferation, differentiation, and tissue homeostasis, particularly within the Hippo signaling pathway. Since TAZ does not directly bind to DNA, it largely relies on its protein-protein interaction network to perform its functions, necessitating a detailed characterization of the TAZ interactome. To achieve this, a GFP-Nanotrap-based affinity purification approach combined with LC-MS/MS protein identification was employed to document a comprehensive list of both known and novel components of the TAZ interactome in myogenic cells.

Characterization of protein interactions is a fundamental goal in the post-genomic era. Here, we document a generally applicable approach to identify cellular protein interactomes using a combination of nanobody based affinity purification (A-P) coupled with tandem mass spectrometry (MS/MS). The Hippo signalling regulator TAZ functions as a transcriptional co-repressor/activator depending on its protein:protein interaction (PPI) network, we therefore undertook an unbiased proteomic screen to ide  ...[more]
