| Protein Effect | unknown |
| Gene Variant Descriptions | RAD51C V239G does not lie within any known functional domains of the Rad51c protein (UniProt.org). V239G retains functional homology-directed DNA repair activity in culture, maintains the ability to form stable complexes with Xrcc3 in in vitro assays, and rescues viability and cisplatin hypersensitivity in Rad51c-deficient cells, but forms a complex with Rad51b, Rad51d and Xrcc2 that binds DNA but demonstrates partially reduced ATPase activity and defective Rad51 filament formation in in vitro assays, and impaired replication fork reversal leading to accumulation of ssDNA breaks in cell culture, and results in reduced interaction with Rad51d in yeast assays (PMID: 40670332), and therefore, its effect on Rad51c protein function is unknown. |
