Molecular basis for assembly of the shieldin complex and its implications for NHEJ
Abstract
Shieldin, including SHLD1, SHLD2, SHLD3 and REV7, functions to suppress the DNA termini nucleolytic resection during non-homologous end joining (NHEJ). Here the authors present the crystal structure of the SHLD3-REV7-SHLD2 ternary complex revealing insights into the mechanism of the complex.
