somatic diversification of T cell receptor genes by N region addition

The addition of variable numbers of random nucleotides by terminal deoxytransferase in the N regions of T cell receptor genes. N regions are found at the V-D, D-D, V-J, and D-J recombinational junctions, depending on the T cell receptor gene.

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.

prostaglandin J receptor activity

Combining with prostaglandin J (PGJ(2)), a metabolite of prostaglandin D (PGD(2)) to initiate a change in cell activity.

somatic diversification of immunoglobulin genes by N region addition

The addition of variable numbers of random nucleotides by terminal deoxytransferase in the N regions of heavy chain immunoglobulin genes. N regions are found at the V-D and D-J recombinational junctions.

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.

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).

aldose beta-D-fructosyltransferase activity

Catalysis of the reaction: alpha-D-aldosyl1 beta-D-fructoside + D-aldose2 = D-aldose1 + alpha-D-aldosyl2 beta-D-fructoside.

lacto-N-biosidase activity

Catalysis of the reaction: H2O + beta-D-Gal-(1,3)-beta-D-GlcNAc-(1,3)-beta-D-Gal-(1,4)-D-Glc = beta-D-Gal-(1,4)-D-Glc + beta-D-Gal-(1,3)-D-GlcNAc.
