Recombination-activating gene 1 (RAG1) protein is a critical enzyme in the adaptive immune system, playing a central role in V(D)J recombination—a site-specific DNA rearrangement process that generates diverse antigen receptors (T-cell receptors and immunoglobulins) in developing lymphocytes. Discovered in the 1990s, RAG1. along with its partner RAG2. forms an endonuclease complex that introduces double-strand breaks at specific recombination signal sequences (RSSs) flanking variable gene segments. This enables the combinatorial assembly of gene segments, driving immune diversity essential for recognizing pathogens. Structurally, RAG1 contains a catalytic core with a conserved DDE motif (aspartate, aspartate, glutamate residues) responsible for DNA cleavage, while its non-core regions aid in RSS binding and coordination with RAG2. Though evolutionarily related to transposases, RAG1 activity is tightly regulated to prevent genomic instability. Defects in RAG1 cause severe immunodeficiency disorders, such as SCID (severe combined immunodeficiency) and Omenn syndrome, highlighting its non-redundant role in lymphocyte development. Research on RAG1 continues to uncover its interactions with chromatin modifiers, repair proteins, and regulatory mechanisms, offering insights into immune disorders, autoimmunity, and lymphoid malignancy. Its unique function also makes it a tool in synthetic biology for targeted DNA editing applications.
