Sgs1, also known as small growth suppressor 1,[1] is a DNA helicase protein found in Saccharomyces cerevisiae. It is a homolog of the bacterial RecQ helicase. Like the other members of the RecQ helicase family, Sgs1 is important for DNA repair. In particular, Sgs1 collaborates with other proteins to repair double-strand breaks during homologous recombination in eukaryotes.[2]
