Pre-mRNA Splicing Machinery (Spliceosome)

Target
Spliceosome
Molecular classification
Ribonucleoprotein complex, RNA-binding protein, Enzyme complex
01

Overview

The pre-mRNA splicing machinery, primarily the spliceosome, is a dynamic molecular system responsible for removing introns from pre-mRNA and ligating exons to form mature mRNA. This process is crucial for proper gene expression in eukaryotes. Dysfunction of the splicing machinery or misregulation of splicing can lead to disease states.
