Genetic and cytological characterization of the recombination protein RAD-51 in Caenorhabditis elegans
We investigated the role of Caenorhabditis elegans rad-51 during meiotic prophase. We showed that rad-51 mutant worms are viable, have no defects in meiotic homology recognition and synapsis butExpand
Mechanistic insight into site-restricted monoubiquitination of FANCD2 by Ube2t, FANCL, and FANCI.
A key step in the Fanconi anemia (FA) tumor suppressor pathway is the site-specific monoubiquitination of the FANCD2 protein. Genetic studies indicate that this crucial modification requires eightExpand
The vertebrate Hef ortholog is a component of the Fanconi anemia tumor-suppressor pathway
The helicase-associated endonuclease for fork-structured DNA (Hef) is an archaeabacterial protein that processes blocked replication forks. Here we have isolated the vertebrate Hef ortholog andExpand
C. elegans RAD-5/CLK-2 defines a new DNA damage checkpoint protein
BACKGROUND In response to genotoxic stress, cells activate checkpoint pathways that lead to a transient cell cycle arrest that allows for DNA repair or to apoptosis, which triggers the demise ofExpand
The Walker B motif in avian FANCM is required to limit sister chromatid exchanges but is dispensable for DNA crosslink repair
FANCM, the most highly conserved component of the Fanconi Anaemia (FA) pathway can resolve recombination intermediates and remodel synthetic replication forks. However, it is not known if theseExpand
Structure of HHARI, a RING-IBR-RING ubiquitin ligase: autoinhibition of an Ariadne-family E3 and insights into ligation mechanism.
A distinct mechanism for ubiquitin (Ub) ligation has recently been proposed for the RING1-IBR-RING2 (RBR) family of E3s: an N-terminal RING1 domain recruits a thioester-linked intermediate complexExpand
The Caenorhabditis elegans Homolog of Gen1/Yen1 Resolvases Links DNA Damage Signaling to DNA Double-Strand Break Repair
DNA double-strand breaks (DSBs) can be repaired by homologous recombination (HR), which can involve Holliday junction (HJ) intermediates that are ultimately resolved by nucleolytic enzymes. AnExpand
Multiple Genetic Pathways Involving the Caenorhabditis elegans Bloom's Syndrome Genes him-6, rad-51, and top-3 Are Needed To Maintain Genome Stability in the Germ Line
ABSTRACT Bloom's syndrome (BS) is an autosomal-recessive human disorder caused by mutations in the BS RecQ helicase and is associated with loss of genomic integrity and an increased incidence ofExpand
TRIAD1 and HHARI bind to and are activated by distinct neddylated Cullin-RING ligase complexes
RING (Really Interesting New Gene)‐in‐between‐RING (RBR) enzymes are a distinct class of E3 ubiquitin ligases possessing a cluster of three zinc‐binding domains that cooperate to catalyse ubiquitinExpand
Two Distinct Types of E3 Ligases Work in Unison to Regulate Substrate Ubiquitylation
Hundreds of human cullin-RING E3 ligases (CRLs) modify thousands of proteins with ubiquitin (UB) to achieve vast regulation. Current dogma posits that CRLs first catalyze UB transfer from an E2 toExpand
