What's a GeneRIF?

STAG3 deficiency has a major effect on DNA double-strand breaks number even in the absence of PRDM9, showing that its role is not restricted to canonical PRDM9-activated hotspots.
Title: Prdm9 and Meiotic Cohesin Proteins Cooperatively Promote DNA Double-Strand Break Formation in Mammalian Spermatocytes.
Our genetic analysis demonstrates that cohesins containing STAG3 and REC8 are the main complex required for centromeric cohesion, and RAD21L cohesins are required for normal clustering of pericentromeric heterochromatin. Furthermore, the STAG3/REC8 and STAG3/RAD21L cohesins are the primary cohesins required for axis formation.
Title: Genetic Interactions Between the Meiosis-Specific Cohesin Components, STAG3, REC8, and RAD21L.
our data suggests that STAG3 is required for structural changes of chromosomes that mediate chromosome pairing and synapsis, DNA repair and progression of meiosis.
Title: Meiosis-specific cohesin component, Stag3 is essential for maintaining centromere chromatid cohesion, and required for DNA repair and synapsis between homologous chromosomes.
STAG3 is a strong candidate gene for male infertility
Title: STAG3 is a strong candidate gene for male infertility.
STAG3-REC8 cohesin complexes have a critical role in supporting meiotic chromosome structure and functions.
Title: STAG3-mediated stabilization of REC8 cohesin complexes promotes chromosome synapsis during meiosis.
STAG3 emerges as the key STAG cohesin involved in major functions of meiotic cohesin.

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.
