The ssDNA-binding protein MEIOB acts as a dosage-sensitive regulator of meiotic recombination.
Title: The ssDNA-binding protein MEIOB acts as a dosage-sensitive regulator of meiotic recombination.
Two mutations (N64I and S67 deletion) in MEIOB cause self-aggregation of MEIOB and sharply reduced protein half-life. In addition to a role in early meiotic recombination, MEIOB/SPATA22 plays a role in late meiotic recombination, i.e., in crossover formation, in a dosage-dependent manner.
Title: The ssDNA-binding protein MEIOB acts as a dosage-sensitive regulator of meiotic recombination.
Aspartic acid 383 (D383) in MEIOB is essential for meiosis in mice. Isocotoin, a small molecule, inhibits the MEIOB-SPATA22 interaction and promotes their degradation in HEK293 cells in a dose-dependent manner.
Title: A cell-based high-content screen identifies isocotoin as a small molecule inhibitor of the meiosis-specific MEIOB-SPATA22 complex†.
We find that MEIOB and SPATA22 form an obligate complex and contain defined interaction domains
Title: Meiosis-specific proteins MEIOB and SPATA22 cooperatively associate with the single-stranded DNA-binding replication protein A complex and DNA double-strand breaks.
MEIOB and SPATA22 form an obligate complex and contain defined interaction domains. A single residue D383 in MEIOB is indispensable for the MEIOB-SPATA22 interaction. The MEIOB/SPATA22 complex interacts with the RPA heterotrimeric complex in a collaborative manner.
Title: Meiosis-specific proteins MEIOB and SPATA22 cooperatively associate with the single-stranded DNA-binding replication protein A complex and DNA double-strand breaks.
MEIOB is required for meiotic recombination and chromosomal synapsis.
Title: MEIOB exhibits single-stranded DNA-binding and exonuclease activities and is essential for meiotic recombination.
MEIOB is a meiosis-specific paralogue of RPA1. MEIOB colocalizes with RPA in foci on meiotic chromosomes. MEIOB binds to single-stranded DNA and exhibits 3'-5' exonuclease activity. MEIOB forms a complex with RPA and with SPATA22. Chromatin localization and stability of MEIOB depends on SPATA22 and vice versa. MEIOB is essential for meiotic recombination in both sexes.
Title: MEIOB exhibits single-stranded DNA-binding and exonuclease activities and is essential for meiotic recombination.

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.
