The protein encoded by this gene is involved in antibody and T-cell receptor V(D)J recombination. RAG-1 is involved in recognition of the DNA substrate, but stable binding and cleavage activity also requires RAG-2. The RAG-1/2 complex recognizes recombination signal sequences (RSSs) that flank the V, D and J regions in the genes that encode the heavy and light chains of antibodies and components of T-cell receptors. The complex binds to the RSSs and nicks the DNA. This leads t…
