Fusiosplicing

Fusiosplicing is a process by which two or more exons from different genes are joined together to form a single mRNA molecule. This process is a type of alternative splicing, where the pre-mRNA is not spliced in the canonical way, but instead, exons from different genes are combined. Fusiosplicing can occur between genes that are located on the same chromosome or on different chromosomes. The process involves the recognition of specific sequences in the pre-mRNA, which are then joined together by the spliceosome, a large ribonucleoprotein complex that catalyzes the splicing reaction. Fusiosplicing can result in the production of novel proteins with unique functions, and it has been implicated in various biological processes, including development, disease, and evolution. The molecular mechanisms underlying fusiosplicing are still not fully understood, and ongoing research aims to elucidate the factors that regulate this process and its role in health and disease.
