Single-stranded DNA-binding protein recruited to replication forks to maintain genome stability (PubMed:28735897). Prevents fork collapse by antagonizing the accumulation of RAD51 at forks to ensure the proper balance of fork remodeling and protection without interfering with the capacity of cells to complete homologous recombination of double-strand breaks (PubMed:28735897). . This is the function of Ensembl gene identifier ENSG00000147231 (RADX, RPA1 related single stranded DNA binding protein, X-linked).
