What's a GeneRIF?

the combination of dynamic light scattering and differential scanning fluorimetry techniques to optimize the stability and homogeneity of recombinant Saw1. The protein expression and purification conditions identified in this study allow for higher recovery of soluble Saw1 and enable the biochemical characterization of the protein.
Title: Large-scale production of recombinant Saw1 in Escherichia coli.
results support a model in which Saw1 and Rad1-Rad10 are recruited as a complex to short and long flaps in all phases of cell cycle, but that Saw1 is only required for recruitment of Rad1-Rad10 to DSBs when long flaps are formed in G1
Title: Saw1 localizes to repair sites but is not required for recruitment of Rad10 to repair intermediates bearing short non-homologous 3' flaps during single-strand annealing in S. cerevisiae.
Saw1 and its sumoylation suggest that Saw1 is a multifunctional scaffold that can facilitate diverse types of DNA repair through its modification and nuclease interactions.
Title: A versatile scaffold contributes to damage survival via sumoylation and nuclease interactions.
Saw1 is required for Synthesis Dependent Strand Annealing double-strand break repair in S. cerevisiae.
Title: SAW1 is required for SDSA double-strand break repair in S. cerevisiae.
Saw1 plays a role in Rad1/Rad10 complex assembly at recombination intermediates in budding yeast.
Title: Role of Saw1 in Rad1/Rad10 complex assembly at recombination intermediates in budding yeast.
Data suggest that Saw1 targets Rad1/Rad10 to Rad52-coated recombination intermediates.
Title: Microarray-based genetic screen defines SAW1, a gene required for Rad1/Rad10-dependent processing of recombination intermediates.
