XLF Interacts with the XRCC4-DNA Ligase IV Complex to Promote DNA Nonhomologous End-Joining
DNA nonhomologous end-joining (NHEJ) is a predominant pathway of DNA double-strand break repair in mammalian cells, and defects in it cause radiosensitivity at the cellular and whole-organism levels. Central to NHEJ is the protein complex containing DNA Ligase IV and XRCC4. By searching for additional XRCC4-interacting factors, we identified a previously uncharacterized 33 kDa protein, XRCC4-li...
متن کاملA human XRCC4–XLF complex bridges DNA
DNA double-strand breaks pose a significant threat to cell survival and must be repaired. In higher eukaryotes, such damage is repaired efficiently by non-homologous end joining (NHEJ). Within this pathway, XRCC4 and XLF fulfill key roles required for end joining. Using DNA-binding and -bridging assays, combined with direct visualization, we present evidence for how XRCC4-XLF complexes robustly...
متن کاملThe nebulin repeat protein Lasp regulates I-band architecture and filament spacing in myofibrils
Mutations in nebulin, a giant muscle protein with 185 actin-binding nebulin repeats, are the major cause of nemaline myopathy in humans. Nebulin sets actin thin filament length in sarcomeres, potentially by stabilizing thin filaments in the I-band, where nebulin and thin filaments coalign. However, the precise role of nebulin in setting thin filament length and its other functions in regulating...
متن کاملNebulin interacts with CapZ and regulates thin filament architecture within the Z-disc.
The barbed ends of actin filaments in striated muscle are anchored within the Z-disc and capped by CapZ; this protein blocks actin polymerization and depolymerization in vitro. The mature lengths of the thin filaments are likely specified by the giant "molecular ruler" nebulin, which spans the length of the thin filament. Here, we report that CapZ specifically interacts with the C terminus of n...
متن کاملAssembly and filament architecture of MamK
Background: The bacterial actin MamK is involved in the organization of bacterial organelles called magnetosomes. Results: MamK is an ATPase and assembles into filaments with a unique architecture. Conclusion: MamK shares features of structure and assembly with other bacterial actin homologs, and has some unique features of its own. Significance: This work will guide future studies to unravel m...
