Homo sapiens

Werner syndrome ATP-dependent helicase

MGS1

Saccharomyces cerevisiae

Protein with DNA-dependent ATPase and ssDNA annealing activities; involved in maintenance of genome; interacts functionally with DNA polymerase delta; homolog of human Werner helicase interacting protein (WHIP); forms nuclear foci upon DNA replication stress
