Biochemistry: The Spliceosomal Peptidyl Prolyl Isomerase Like 1 Interacts with the Low-Complexity Domain of the RNA Binding Protein EWS Modulating Its Phase Separation Behavior (Libich Lab)
August 8, 2025
George L Parra 1, Erich J Sohn 1, Xiaoping Xu 1, David S Libich 1 Abstract RNA-binding protein EWS, a member of the FET (FUS, EWS, TAF15) family, contributes to mRNA biogenesis through roles in transcription, splicing, and RNA transport. Despite evidence linking EWS to spliceosomal complexes, its interactions with spliceosome-associated cyclophilins remain unclear. Here, we describe the first structural and biochemical [...]
