SNRNP70

SRNP70, or U1 small ribonucleoprotein particle 70, is a nuclear protein in eukaryotes that is central to the U1 snRNP complex, which is instrumental in the splicing of pre-mRNA by identifying the 5' splice site and facilitating splice reactions. This protein's function includes the precise binding to pre-mRNA and coordination with other splicing factors to ensure the accuracy of splicing. SRNP70 is crucial for the correct expression of genes and the regulation of splicing patterns. Additionally, it contributes to the chromatin retention of non-coding RNA, significantly influencing gene expression and chromatin state regulation.
