V(D)J recombination - Wikipedia

WebDec 24, 2024 · Antibodies obtain their diversity through 2 processes. The first is called V (D)J (variable, diverse, and joining regions) recombination. During cell maturation, the B cell splices out the DNA of all but one of the genes from each region and combine the three remaining genes to form one VDJ segment. The second stage of recombination occurs ... WebThe TCR (T-cell receptor) is a complex of integral membrane proteins that participate in the activation of T-cells in response to an antigen.
