Abstract The SH3 domain found within a variety of proteins is comprised of generally 60 residues, and participated in protein-protein interactions with proline-rich motifs. Cobll1 was identified as a distinct molecular marker associated with CML progression, and PACSIN2 was discovered a novel Cobll1 binding partner through direct interaction between a SH3 domain of PACSIN2 and three proline-rich motifs of Cobll1. To understand the structural basis of interactions between PACSIN2 and Cobll1, backbone assignments of PACSIN2 SH3 domain were performed. Furthermore, three proline-rich peptides of Cobll1 were titrated to ¹⁵N-labeled PACSIN2 SH3 domain in various ratios. Our chemical shift changes data and conserved SH3 sequence alignment will be helpful to analyze fundamental molecular basis related to the interaction between PACSIN2 and Cobll1.
