The homozygotes (knock-in mice with Xrcc2-c.T41C/p.Leu14Pro mutation) survived and exhibited meiotic arrest, azoospermia, premature ovarian failure and infertility.
Title: XRCC2 mutation causes meiotic arrest, azoospermia and infertility.
involvement of ZNF281 in the cellular response to genotoxic stress through the control exercised on the expression of genes that act in different repair mechanisms
Title: ZNF281 contributes to the DNA damage response by controlling the expression of XRCC2 and XRCC4.
Data show that XRCC2 and other homologous recombination proteins, including the key recombinase RAD51, co-localize with the centrosome, potentially to coordinate the deployment of a DNA damage response at vulnerable phases of the cell cycle.
Title: Homologous recombination proteins are associated with centrosomes and are required for mitotic stability.
These findings indicate that Xrcc2 haploinsufficiency reduces spontaneous tumor incidence on an Apc(min/+) background but increases the tumorigenic response to radiation.
Title: Xrcc2 modulates spontaneous and radiation-induced tumorigenesis in Apcmin/+ mice.
An important function of XRCC2 is to enhance the activity of RAD51, so that the loss of XRCC2 results in a severe delay in the early response of RAD51 to DNA damage.
Title: The importance of XRCC2 in RAD51-related DNA damage repair.
DNA replication licensing factor MCM2 and DNA mismatch repair (MMR) protein MSH2 were confirmed to be present in co-precipitations with MmXRCC2.

Xrcc2 is important to preserve or restore replication forks during rapid clonal expansion of developing lymphocytes.
Title: Homologous recombination is necessary for normal lymphocyte development.
ATP hydrolysis by Rad51 is more important for some homologous recombination functions than it is for other aspects of DNA repair

the normal developmental programme is perturbed in Xrcc2-/- embryonic tissues, particularly during neurogenesis and somitogenesis
Title: A role for Xrcc2 in the early stages of mouse development.
Order-of-magnitude higher levels of chromosomal alterations are sustained in primary or immortal Xrcc2(-/-) embryonic fibroblasts.

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
