The enzymology of the process is discussed, followed by studies on DSB repair in living cells, and a historical context for the current view of HR is provided and how DSBs are processed during HR as well as interactions with other D SB repair pathways are described.
Abstract
In this review, we discuss the repair of DNA double-strand breaks (DSBs) using a homologous DNA sequence (i.e., homologous recombination [HR]), focusing mainly on yeast and mammals. We provide a historical context for the current view of HR and describe how DSBs are processed during HR as well as interactions with other DSB repair pathways. We discuss the enzymology of the process, followed by studies on DSB repair in living cells. Whenever possible, we cite both original articles and reviews to aid the reader for further studies.

CATI: an efficient gene integration method for rodent and primate embryos by MMEJ suppression

TL;DR: Using CasRx to downregulate a key microhomology-mediated end-joining (MMEJ) factor, Polymerase Q (Polq), improved the targeted integration efficiency of linearized DNA fragments and single-strand oligonucleotides (ssODN) in mouse embryos and offspring as mentioned in this paper .

RPA phosphorylation regulates DNA resection

TL;DR: It is established that pRPA is a critical regulator of DNA repair enzymes and provides a feedback loop between the DDR and DNA resection termination and phosphorylated RPA (pRPA) inhibitsDNA resection via regulation of BLM helicase.

Modulating MCM Levels Causes Differential Loading at Origins of Replication and Changes Replication Timing

Livio Dukaj
TL;DR: DNA replication in budding yeast initiates at sequence-specific loci called origins of replication, and MCM is placed in a key role in establishing a replication timing program that is reproduced but arises from stochastic activation of origins, as has been observed in yeast and higher eukaryotes.

Rdh54 stabilizes Rad51 at displacement loop intermediates to regulate genetic exchange between chromosomes

TL;DR: The data indicates that RDH54 regulates DNA sequence exchange between chromosomes by limiting the disruption of Rad51 at an early HR intermediate called the displacement loop (D-loop), and proposes a model for how Rdh54 may effectively regulate information transfer during homologous recombination.

TL;DR: The type II prokaryotic CRISPR (clustered regularly interspaced short palindromic repeats)/Cas adaptive immune system has been shown to facilitate RNA-guided site-specific DNA cleavage as discussed by the authors.

Multiplex Genome Engineering Using CRISPR/Cas Systems

TL;DR: Two different type II CRISPR/Cas systems are engineered and it is demonstrated that Cas9 nucleases can be directed by short RNAs to induce precise cleavage at endogenous genomic loci in human and mouse cells, demonstrating easy programmability and wide applicability of the RNA-guided nuclease technology.

Efficient genome editing in zebrafish using a CRISPR-Cas system

TL;DR: It is shown that the CRISPR-Cas system functions in vivo to induce targeted genetic modifications in zebrafish embryos with efficiencies similar to those obtained using zinc finger nucleases and transcription activator-like effector nucleases.
