Zoolog. Syst. Evol. Res. 0:0-0(2019). 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.
