RecQ helicase-Topo III complex Overview

GO Annotations consist of four mandatory components: a gene product, a term from one of the three Gene Ontology (GO) controlled vocabularies (Molecular Function, Biological Process, and Cellular Component), a reference, and an evidence code.


Summary
Required for both the early and late steps of DNA double-strand break (DSB) via dissolution of double Holliday junctions. Early in the repair of a two-ended DSB, the complex contributes to DSB end resection by facilitating the formation of a single-strand 3-prime overhang on which the homologous recombination (HR) factor Rad51 (P25454) filament assembles. The complex has also been implicated in the unwinding of strand invasion after extension of the invading 3-prime end by DNA synthesis to promote DSB repair by synthesis-dependent strand annealing, as well as reversal of strand invasion prior to 3-prime end extension. Through these functions, the complex promotes non-crossover outcomes of HR and regulates HR levels.
GO Slim Terms

The yeast GO Slim terms are higher level terms that best represent the major S. cerevisiae biological processes, functions, and cellular components. The GO Slim terms listed here are the broader parent terms for the specific terms to which this gene product is annotated, and thus represent the more general processes, functions, and components in which it is involved.
