Around 1,000 RBPs account for these functions in mammalian cells. The total number of RBPs has recently more than tripled to include many ""well-known"" proteins such as metabolic enzymes or membrane proteins, sparking debate about the biological relevance of their RNA binding. We examine the experimental basis underlying the dramatic expansion of the RBPome, consider arguments that challenge its relevance, and discuss recent data that describe new RBP and RNA functions.

Both elements are essential for the progression of tumors. While recent research has increasingly illuminated their individual mechanisms, the intricate network interplay between them still requires further exploration. This article has provided a comprehensive review of the roles played by RNA-binding proteins and their associated non-coding RNAs in tumor biology. It delves into the intricate functions of various RNA-binding proteins in tumors, including their involvement in alternative splicing, m6A modification, alternative polyadenylation, and phase separation. Furthermore, it highlights the diverse and significant roles of different non-coding RNAs, such as microRNAs, long non-coding RNAs, and circRNAs, in tumor progression. The interaction between RNA-binding proteins and regulated non-coding RNAs is also explored, providing insights into their collective impact on metabolic reprogramming, immunity, drug resistance, metastasis, and ferroptosis. This in-depth exploration not only deepens our understanding of the mechanisms underlying tumorigenesis but also lays a foundation for developing innovative therapeutic strategies.

Their interactions with RNA molecules govern critical processes such as mRNA splicing, stability, localization, and translation, which are essential for proper cellular function. These proteins interact with RNA molecules and other proteins to form ribonucleoprotein complexes (RNPs), hence controlling the fate of target RNAs. The interaction occurs via RNA recognition motif, the zinc finger domain, the KH domain and the double stranded RNA binding motif (all known as RNA-binding domains (RBDs). These domains are found within the coding sequences (intron and exon domains), 5' untranslated regions (5'UTR) and 3' untranslated regions (3'UTR). Dysregulation of RBPs can lead to genomic instability, contributing to various pathologies, including cancer neurodegenerative diseases, and metabolic disorders. This study comprehensively explores the multifaceted roles of RBPs in genetic stability, highlighting their involvement in maintaining genomic integrity through modulation of RNA processing and their implications in cellular signalling pathways. Furthermore, it discusses how aberrant RBP function can precipitate genetic instability and disease progression, emphasizing the therapeutic potential of targeting RBPs in restoring cellular homeostasis. Through an analysis of current literature, this study aims to delineate the critical role of RBPs in ensuring genetic stability and their promise as targets for innovative therapeutic strategies.
