SPO11 Spo11p

Spo11, Rec12, Spo11p
Meiotic recombination and chromosome segregation require the formation of double-strand breaks (DSBs) in paired chromosome homologs. During meiosis in yeast, a meiotic recombination protein is covalently-linked to the 5' end of DSBs and is essential for the formation of DSBs. The protein encoded by this gene is similar in sequence and conserved features to the yeast meiotic recombination protein. The encoded protein belongs to the TOP6A protein family. Several transcript variants encoding different isoforms have been found for this gene, but the full-length nature of only two of them have been described. [provided by RefSeq, Jul 2008] (from NCBI)

Papers on Spo11
[Association of SPO11 and GST gene polymorphisms with idiopathic male infertility in ethnic Han Chinese].
Gao et al., Zhengzhou, China. In Zhonghua Yi Xue Yi Chuan Xue Za Zhi, Jan 2016
OBJECTIVE: To explore the possible roles of polymorphisms of SPO11 and glutathionine S-transferase (GST) genes in idiopathic male infertility in a ethnic Han Chinese population from Henan.
A surge of late-occurring meiotic double-strand breaks rescues synapsis abnormalities in spermatocytes of mice with hypomorphic expression of SPO11.
Barchi et al., Roma, Italy. In Chromosoma, Nov 2015
In mammals, during prophase of meiosis I, homologous chromosomes align and synapse through a recombination-mediated mechanism initiated by the introduction of DNA double-strand breaks (DSBs) by the SPO11 protein.
DNA methylation restrains transposons from adopting a chromatin signature permissive for meiotic recombination.
Bourc'his et al., Paris, France. In Genes Dev, Jul 2015
Indeed, H3K4me3 marks gained over transcriptionally active transposons correlate with formation of SPO11-dependent double-strand breaks and recruitment of the DMC1 repair enzyme in Dnmt3L(-/-) meiotic cells, whereas these features are normally exclusive to meiotic recombination hot spots.
MEI4 – a central player in the regulation of meiotic DNA double-strand break formation in the mouse.

Meiotic DSB formation is catalyzed by SPO11 and their repair takes place on meiotic chromosome axes.
Identification of the meiotic toolkit in diatoms and exploration of meiosis-specific SPO11 and RAD51 homologs in the sexual species Pseudo-nitzschia multistriata and Seminavis robusta.
Ferrante et al., Napoli, Italy. In Bmc Genomics, 2014
The two sexual species Pseudo-nitzschia multistriata and Seminavis robusta were used to explore the expression of meiosis-related genes: RAD21, SPO11-2, RAD51-A, RAD51-B and RAD51-C were upregulated during meiosis, whereas other paralogs in these families showed no differential expression patterns, suggesting that they may play a role during vegetative divisions.

Data support a role for SPO11alpha in mid- to late prophase, presumably acting as a topoisomerase, that would be conserved in male and female meiocytes.
