NCBI Protein Information
double-stranded DNA binding protein
NCBI Summary
This gene is predicted to encode a protein that forms part of the topoisomerase VI complex. BIN4 is a nuclear-localized protein that can bind DNA. bin4 mutants are brassinolide-insensitive dwarves with severely reduced cell size in leaves, roots, and hypocotyls. Proper development of root hairs and trichomes is also disrupted in bin4 mutants and they have elevated levels of double strand breaks in their cotyledon cells.

UniProt Comments
Component of the DNA topoisomerase VI complex. Binds to DNA. Required for chromatin organization and progression of endoreduplication cycles. The loss of BIN4 activates the ATM- and ATR-dependent DNA damage responses in postmitotic cells and induces the ectopic expression of the mitotic G2/M-specific cyclin B1;1 gene in non-dividing cells.
