PALB2 self-interaction controls homologous recombination

PALB2 is essential for BRCA2 anchorage to nuclear structures and for homologous recombinational repair of DNA double-strand breaks. Here, we report that the N-terminal coiled-coil motif of PALB2 regulates its self-association and homologous recombination. Monomeric PALB2 shows higher efficiency to bind DNA and promotes RAD51 filament formation with or without the inhibitory effect of Replicatio...

MRG15 is a novel PALB2-interacting factor involved in homologous recombination.

PALB2 is an integral component of the BRCA complex important for recombinational DNA repair. However, exactly how this activity is regulated in vivo remains unexplored. Here we provide evidence to show that MRG15 is a novel PALB2-associated protein that ensures regulated recombination events. We found that the direct interaction between MRG15 and PALB2 is mediated by an evolutionarily conserved...

Designing E1 Deleted Adenoviral Vector by Homologous Recombination

Adenoviruses are used extensively to deliver genes into mammalian cells, particularly where there is a requirement for high-level expression of transgene products in cultured cells, or for use as recombinant viral vaccines or in gene therapy. In spite of their usefulness, the construction of adenoviral vectors (AdV) is a cumbersome and lengthy process that is not readily amenable to the generat...

A PALB2-interacting domain in RNF168 couples homologous recombination to DNA break-induced chromatin ubiquitylation

DNA double-strand breaks (DSB) elicit a ubiquitylation cascade that controls DNA repair pathway choice. This cascade involves the ubiquitylation of histone H2A by the RNF168 ligase and the subsequent recruitment of RIF1, which suppresses homologous recombination (HR) in G1 cells. The RIF1-dependent suppression is relieved in S/G2 cells, allowing PALB2-driven HR to occur. With the inhibitory imp...

PALB2 is an integral component of the BRCA complex required for homologous recombination repair.

Mutations in breast cancer susceptibility gene 1 and 2 (BRCA1 and BRCA2) predispose individuals to breast and ovarian cancer development. We previously reported an in vivo interaction between BRCA1 and BRCA2. However, the biological significance of their association is thus far undefined. Here, we report that PALB2, the partner and localizer of BRCA2, binds directly to BRCA1, and serves as the ...
