Protein Information (annotations from UniProt)

Database IDHIV0002468
UniProt IDO95072
Primary gene name(s)REC8
Synonym gene name(s)REC8L1
Protein nameMeiotic recombination protein REC8 homolog
Protein functionRequired during meiosis for separation of sister chromatids and homologous chromosomes. Proteolytic cleavage of REC8 on chromosome arms by separin during anaphase I allows for homologous chromosome separation in meiosis I and cleavage of REC8 on centromeres during anaphase II allows for sister chromatid separation in meiosis II, By similarity. {ECO:0000250}.
Subcellular locationNucleus {ECO:0000250|UniProtKB:Q6AYJ4}. Chromosome {ECO:0000250|UniProtKB:Q6AYJ4}. Chromosome, centromere {ECO:0000250|UniProtKB:Q6AYJ4}. Note=In meiotic chromosomes, localized along axial elements in prophase from the leptotene to diplotene stages. At later prophase stages, diakinesis and metaphase I, localized along interstitial axes of chromosomes including both centromere and arm regions. No longer detected in arm regions in anaphase I but persists on centromere regions until metaphase II. Localised to centromeres and spindle poles in endopolyploid tumor cells. {ECO:0000250|UniProtKB:Q6AYJ4}.
