These data suggest that Tex19.1 and Ubr2 are required for mouse spermatocytes to accumulate sufficient Spo11-dependent recombination to ensure that the homology search is consistently successful, and reveal a hitherto unknown genetic pathway promoting meiotic recombination in mammals.
Title: Tex19.1 promotes Spo11-dependent meiotic recombination in mouse spermatocytes.
If SPO11 expression is reduced and DNA double-strand breaks at zygonema are decreased (approximately 40 % below wild-type level), meiotic chromosome pairing is normal.

our results indicate that in addition to asynapsis, persistent SPO11-induced DSBs are important for the initiation of MSCI and MSUC, and that SPO11-independent DNA repair foci contribute to the MSUC response in oocytes.
Title: SPO11-independent DNA repair foci and their role in meiotic silencing.
Mice with greater or fewer copies of the Spo11 gene--with correspondingly greater or fewer numbers of early recombination foci--exhibited relatively invariant crossover numbers.

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.
