ALTERNATIVE RNA SPLICING Meaning and
Definition
-
Alternative RNA splicing is a crucial cellular process that occurs during gene expression and involves the removal of introns from pre-messenger RNA (pre-mRNA) molecules, as well as the rearrangement and joining of exons to generate mature mRNA molecules. This mechanism provides cells with the opportunity to increase their protein diversity by producing multiple mRNA transcripts from a single gene, resulting in the expression of distinct protein isoforms.
During alternative RNA splicing, different combinations of exons are selected and joined together, resulting in the production of mRNA molecules that encode proteins with altered functions, subcellular localization, or regulatory properties. This process is regulated by complex interactions between the spliceosome, a molecular machinery responsible for splicing events, and other proteins that bind to specific RNA sequences and influence splicing outcomes.
Alternative RNA splicing plays a fundamental role in various biological processes, including development, tissue-specific gene expression, and adaptation to changing environmental conditions. It gives rise to a diverse proteome, allowing cells to fulfill distinct functional requirements without the need for an excessive number of genes. Moreover, alternative RNA splicing contributes to the complexity of multicellular organisms, enabling intricate cellular responses and specialized cellular functions.
Understanding the intricacies of alternative RNA splicing is vital for unraveling the molecular basis of numerous genetic disorders and diseases. It provides insights into the regulation of gene expression and enables the identification of potential therapeutic targets.
