Abstract: The human Bloom Syndrome DNA helicase BLM and its yeast ortholog Sgs1 are large proteins that are well-known for their role in maintaining genome stability. However, the function of the N-terminal halves of these proteins is largely unknown - even though genetic analysis in yeast indicates that they are critical for Sgs1 function in-vivo. We have now performed biochemical studies on this 650 aa portion of the protein. We have identified a region that binds DNA and will describe its biochemical activities. A second approach to understanding Sgs1 function involves the study of genes required in the absence of SGS1 (1). Such synthetic-lethal screens have identified genes involved in the regulation of sumoylated proteins, such as the Slx5-Slx8 SUMO-dependent Ub ligase (2), but not the more common SUMO regulators such as the SUMO E1, E2, E3s, or Ulps. I will describe the activity of a new synthetic interactor, Wss1, involved in regulating the stability of sumoylated proteins. The results suggest that recombination-dependent DNA repair is regulated by a unique form of sumoylation. 1. Mullen, J. R., Kaliraman, V., Ibrahim, S. S., and Brill, S. J. (2001).
