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