Article Abstract
TAR RNA binding protein (TRBP) is a double-stranded RNA binding protein involved in various biological processes like cell growth, development, death, etc. The protein exists as two isoforms TRBP2 and TRBP1. TRBP2 contains additional 21 amino acids at its N-terminus, which are proposed to be involved in its membrane localization, when compared to TRBP1. The resonance assignment (19-228) of the double-stranded RNA binding domains (dsRBD 1 and 2) of TRBP2 has been reported earlier. Here, we report H, C and N resonance assignment for dsRBD1 of TRBP2 (1-105) containing the additional N-terminal residues. This assignment will provide deeper insights to understand the effect of these residues on the structure and dynamics of TRBP2 and would therefore help in further elucidating the differences in the role of these isoforms.

Traditional live attenuated vaccines (LAVs) are typically developed through serial passaging or genetic engineering to introduce specific mutations or deletions. While viral RNA secondary or tertiary structures have been well-documented for their multiple functions, including binding with specific host proteins, their potential for LAV design remains largely unexplored. Herein, using Zika virus (ZIKV) as a model, we demonstrate that targeted disruption of the primary sequence or tertiary structure of a specific viral RNA element responsible for Musashi-1 (MSI1) binding leads to a tissue-specific attenuation phenotype in multiple animal models.

Chemotherapeutic resistance is a significant issue in the treatment of breast cancer, which is related to pyroptosis inhibition. Increasing evidence suggests that long non-coding RNAs (lncRNAs) contribute to tumorigenesis and drug resistance. In this study we investigated the role of the lncRNA STMN1P2 in doxorubicin resistance in breast cancer, as well as its correlation with pyroptosis inhibition.

RNA-protein interactions critically regulate gene expression and cellular processes, yet their comprehensive mapping remains challenging due to their structural diversity. We introduce PRIM-seq (protein-RNA interaction mapping by sequencing), a method for concurrent de novo identification of RNA-binding proteins and their associated RNAs. PRIM-seq generates unique chimeric DNA sequences by proximity ligation of RNAs with protein-linked DNA barcodes, which are subsequently decoded through sequencing.

Several genes in the mitochondria of angiosperms are interrupted by introns, and their posttranscriptional excision involves numerous nucleus-encoded auxiliary factors. Most of these factors are of eukaryotic origin, among them members of the pentatricopeptide-repeat (PPR) family of RNA-binding proteins. This family divides into the PLS and P classes, with PLS-class proteins typically participating in C-to-U mRNA editing and P-class members contributing to transcript stabilization and intron splicing.

E3 ubiquitin ligases regulate the cellular proteome proteasome-dependent protein degradation; however, there exist limited studies outlining their non-canonical functions. RNA-binding ubiquitin ligases (RBULs) represent a subset of E3 ligases that harbour RNA-binding domains, making them uniquely positioned to function as both RNA-binding proteins and E3 ligases. Our initial microarray screen for E3 ligases from mouse cortical neural progenitor cells identified MEX3B, a known RNA-binding ubiquitin ligase, to be differentially expressed.
