WebRAG1 and RAG2 form a tetramer nuclease to initiate V (D)J recombination in developing T and B lymphocytes. The RAG1 protein evolves from a transposon ancestor and possesses nuclease activity that requires interaction with RAG2. Here, we show that the human RAG1 aggregates in the nucleus in the absence of RAG2, exhibiting an extremely low V (D)J ... WebTo understand the distinct functions of RAG1 and RAG2 in signal recognition, we have compared the DNA binding activities of RAG1 alone and RAG1 plus RAG2 by gel retardation and footprinting analyses. RAG1 exhibits only a three- to fivefold preference for binding DNA containing an RSS over random sequence DNA.

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.
