SFRS12 Inhibitors

FRS12 inhibitors represent a class of chemical compounds designed to modulate the activity of Serine/Arginine-Rich Splicing Factor 12 (SFRS12), a key player in the complex process of mRNA splicing. mRNA splicing is a critical mechanism in eukaryotic cells that enables the removal of introns and the joining of exons, ultimately determining the mature mRNA transcript that guides protein synthesis. SFRS12, a member of the SR protein family, plays a pivotal role in splicing regulation by binding to pre-mRNA at specific splice sites and facilitating spliceosome assembly. The modulation of SFRS12 activity has garnered significant attention in the field of molecular biology and cell biology due to its implications in controlling alternative splicing, which can lead to the production of diverse protein isoforms with distinct functions.

These SFRS12 inhibitors are chemical entities specifically designed to interfere with SFRS12's functions within the spliceosome. Mechanistically, they target either SFRS12 directly or other components of the spliceosome, disrupting the precise recognition of splice sites during splicing. Many of these inhibitors exhibit binding affinities to SFRS12 or other spliceosomal components, blocking their normal interactions with pre-mRNA substrates. This interference results in altered splicing patterns, to generate aberrant mRNA isoforms. Consequently, SFRS12 inhibitors have become valuable tools in molecular biology research for dissecting the intricate network of alternative splicing events, shedding light on the functional consequences of splicing variants and their implications in cellular processes beyond applications. Researchers continue to investigate and refine these inhibitors, contributing to our understanding of the fundamental role SFRS12 plays in mRNA splicing regulation.
