Ecol. 24:3706-3722(2015). CC -!- FUNCTION: Catalytic component of the RAG complex, a multiprotein CC complex that mediates the DNA cleavage phase during V(D)J CC recombination. V(D)J recombination assembles a diverse repertoire CC of immunoglobulin and T-cell receptor genes in developing B and T- CC lymphocytes through rearrangement of different V (variable), in CC some cases D (diversity), and J (joining) gene segments. In the CC RAG complex, RAG1 mediates the DNA-binding to the conserved CC recombination signal sequences (RSS) and catalyzes the DNA CC cleavage activities by introducing a double-strand break between CC the RSS and the adjacent coding segment. RAG2 is not a catalytic CC component but is required for all known catalytic activities. DNA CC cleavage occurs in 2 steps: a first nick is introduced in the top CC strand immediately upstream of the heptamer, generating a 3'- CC hydroxyl group that can attack the phosphodiester bond on the CC opposite strand in a direct transesterification reaction, thereby CC creating 4 DNA ends: 2 hairpin coding ends and 2 blunt, 5'- CC phosphorylated ends. {ECO:0000256|RuleBase:RU366024}.
