Zool. (Lond.) 285:128-138(2011). 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. CC {ECO:0000256|RuleBase:RU366024}. CC -!- CATALYTIC ACTIVITY: CC Reaction=S-ubiquitinyl-[E2 ubiquitin-conjugating enzyme]-L-cysteine + CC [acceptor protein]-L-lysine = [E2 ubiquitin-conjugating enzyme]-L- CC cysteine + N(6)-ubiquitinyl-[acceptor protein]-L-lysine.; CC EC=2.3.2.27; Evidence={ECO:0000256|ARBA:ARBA00000900, CC ECO:0000256|RuleBase:RU366024}; CC -!- COFACTOR: CC Name=Mg(2+); Xref=ChEBI:CHEBI:18420; CC Evidence={ECO:0000256|ARBA:ARBA00001946, CC ECO:0000256|RuleBase:RU366024}; CC -!- COFACTOR: CC Name=Mn(2+); Xref=ChEBI:CHEBI:29035; CC Evidence={ECO:0000256|ARBA:ARBA00001936}; CC -!- COFACTOR: CC Name=Mn(2+); Xref=ChEBI:CHEBI:29035; CC Evidence={ECO:0000256|RuleBase:RU366024}; CC Note=Binds 1 divalent metal cation per subunit. Mg(2+) or Mn(2+). CC {ECO:0000256|RuleBase:RU366024}; CC -!- SUBUNIT: Homodimer. {ECO:0000256|RuleBase:RU366024}. CC -!- SUBCELLULAR LOCATION: Nucleus {ECO:0000256|PROSITE-ProRule:PRU00820, CC ECO:0000256|RuleBase:RU366024}. CC -!- DOMAIN: The NBD (nonamer binding) DNA-binding domain mediates the CC specific binding to the nonamer RSS motif by forming a tightly CC interwoven homodimer that binds and synapses 2 nonamer elements, with CC each NBD making contact with both DNA molecules. Each RSS is composed CC of well-conserved heptamer (consensus 5'-CACAGTG-3') and nonamer CC (consensus 5'-ACAAAAACC-3') sequences separated by a spacer of either CC 12 bp or 23 bp. {ECO:0000256|PROSITE-ProRule:PRU00820}. CC -!- SIMILARITY: Belongs to the RAG1 family. {ECO:0000256|PROSITE- CC ProRule:PRU00820, ECO:0000256|RuleBase:RU366024}. CC -!- CAUTION: Lacks conserved residue(s) required for the propagation of CC feature annotation. {ECO:0000256|PROSITE-ProRule:PRU00820}.
