- V(D)J recombination
The process in which immune receptor V, D, and J, or V and J gene segments, depending on the specific receptor, are recombined within a single locus utilizing the conserved heptamer and nonomer recombination signal sequences (RSS).
- T cell receptor V(D)J recombination
The process in which T cell receptor V, D, and J, or V and J gene segments, depending on the specific locus, are recombined within a single locus utilizing the conserved heptamer and nonomer recombination signal sequences (RSS).
- immunoglobulin V(D)J recombination
The process in which immunoglobulin gene segments are recombined within a single locus utilizing the conserved heptamer and nonomer recombination signal sequences (RSS). For immunoglobulin heavy chains V, D, and J gene segments are joined, and for immunoglobulin light chains V and J gene segments are joined.
- somatic diversification of immune receptors by N region addition
The addition of variable numbers of random nucleotides by terminal deoxytransferase in the N regions of heavy chain immunoglobulin and T cell receptor genes. N regions are found at the V-D, D-D, V-J, and D-J recombinational junctions, depending on the immune receptor gene.
- immunoglobulin light chain V-J recombination
The process in which immunoglobulin light chain V and J gene segments are recombined within a single locus utilizing the conserved heptamer and nonomer recombination signal sequences (RSS).
- immunoglobulin heavy chain V-D-J recombination
The process in which immunoglobulin heavy chain V, D, and J gene segments are recombined within a single locus utilizing the conserved heptamer and nonomer recombination signal sequences (RSS).
- collagen type V trimer
A collagen heterotrimer containing type V alpha chains; [alpha1(V)]2alpha2(V) and alpha1(V)alpha2(V)alpha3(V) trimers have been observed; type V collagen triple helices associate to form fibrils.
- DNA-dependent protein kinase complex
A protein complex that is involved in the repair of DNA double-strand breaks and, in mammals, V(D)J recombination events. It consists of the DNA-dependent protein kinase catalytic subunit (DNA-PKcs) and the DNA end-binding heterodimer Ku.
