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 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}.
