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}.
