Journal ArticleDOI

Nonhomologous recombination in mammalian cells: role for short sequence homologies in the joining reaction.

TL;DR: Analysis of 199 independent junctional sequences from seven constructs with different mismatched ends indicates that single-stranded extensions are relatively stable in monkey cells and that the terminal few nucleotides are critical for cell-mediated end joining.
Journal ArticleDOI

Growth Retardation and Leaky SCID Phenotype of Ku70-Deficient Mice

TL;DR: Ku70, Ku80, and DNA-PKcs are subunits of the DNA-dependent protein kinase (DNA-PK), an enzyme implicated in DNA double-stranded break repair and V(D)J recombination, and Ku70-deficient cells were severely impaired for joining of V( D)J coding and recombination signal sequences.
Journal ArticleDOI

Ku86-deficient mice exhibit severe combined immunodeficiency and defective processing of V(D)J recombination intermediates

TL;DR: It is suggested that Ku86 may be required to remodel or disassemble DNA-protein complexes containing broken ends, making them available for further processing and joining in V(D)J recombination in vivo.
Journal ArticleDOI

V(D)J recombination: broken DNA molecules with covalently sealed (hairpin) coding ends in scid mouse thymocytes.

TL;DR: The formation of hairpins at coding ends may be a universal, early step in V(D)J recombination; this would provide a simple explanation for the origin of P nucleotides in coding joints, and suggest a possible role for the scid factor.
