Alternative splicing is a process by which different forms of messenger RNA (mRNA) are produced from a single gene. This process allows a single gene to code for multiple protein isoforms, increasing the diversity and complexity of gene expression. Alternative splicing plays a crucial role in regulating gene expression, protein function, and cellular processes. Dysregulation of alternative splicing has been associated with various diseases, including cancer, neurological disorders, and genetic disorders. Researchers study alternative splicing to understand its mechanisms, functions, and implications for health and disease.
