PG - 121-127 LID - 10.1007/s12104-023-10130-w [doi] AB - The family of AT-rich interactive domain (ARID) containing proteins -Arids- contains 15 members that have almost exclusively been described as DNA-binding proteins. Interestingly, a decade ago the family member Arid5a was found to bind and stabilize mRNAs of immune system key players and thereby account for driving inflammatory and autoimmune diseases. How exactly binding to DNA and RNA is coordinated by the Arid5a ARID domain remains unknown, mainly due to the lack of atom-resolved information on nucleic acid-binding. This in particular applies to the protein's ARID domain, despite the comfortable size of its core unit for NMR-based investigations. Furthermore, the core domain of ARID domains is found to be extended by functionally relevant, often flexible stretches, but whether such elongations are present and crucial for the versatile Arid5a functions is unknown. We here provide a near-complete NMR backbone resonance assignment of the Arid5a ARID domain with N- and C-terminal extensions, which serves as a basis for further studies of its nucleic acid-binding preferences and targeted inhibition by means of NMR. Our data thus significantly contribute to unravelling mechanisms of Arid5a-mediated gene regulation and diseases. CI - (c) 2023. The Author(s).
