SAW1-RAD1-RAD10 endonuclease 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
Endonuclease, which cuts branched DNA structures at the transition between dsDNA and ssDNA. Required for the repair of double-stranded breaks flanked by direct repeat sequences (boxes) which can occur by single-strand annealing, if a 5-prime to 3-prime resection is allowed to progress past the repeats. The complementary single-stranded repeats can anneal, leaving heterologous flaps to be removed by the RAD1-RAD10 endonuclease catalyzing the 3-prime-non-homologous tail removal of the single-strand annealing recombination intermediates, before gap-filling and ligation completes the repair thereby deleting one of the repeats and the intervening sequence. SAW1 contributes to 3-prime tail removal as a mediator between a 3-prime DNA flap substrate and RAD1-RAD10.
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.
