Nuclear magnetic resonance spectral data of the USP7 TRAF and UBL1-2 domains in complex with DNA polymerase ι peptides

This data article is related to the publication ‘DNA polymerase ι interacts with both the TRAF-like and UBL1-2 domains of USP7’ [1]. Ubiquitin-specific protease 7 (USP7) is an essential deubiquitinating enzyme with characterized substrates in many cellular pathways. Established USP7 substrates interact with one of two major binding sites, located on the N-terminal TRAF-like (TRAF) domain and the first and second UBL domains (UBL1-2) within the C-terminal tail. In this article, we present complete nuclear magnetic resonance (NMR) spectroscopy data used to characterize direct interactions between USP7 and its novel substrate DNA polymerase iota (Pol ι), that binds both TRAF and UBL1-2 domains. The detailed description of the NMR data, and the methodology used for processing and analysis, will add to the reproducibility and transparency of the companion research article, as well as aid in the reuse of these data.
