Summary: Enables cysteine-type peptidase activity. Acts upstream of or within homologous chromosome segregation; meiotic spindle organization; and mitotic sister chromatid segregation. Predicted to be active in cytoplasm; microtubule cytoskeleton; and nucleus. Is expressed in several structures, including alimentary system; brain; genitourinary system; integumental system; and respiratory system. Used to study breast cancer. Orthologous to human ESPL1 (extra spindle pole bodies like 1, separase). [provided by Alliance of Genome Resources, Dec 2024]

MicroRNA-202 safeguards meiotic progression by preventing premature SEPARASE-mediated REC8 cleavage.
Title: MicroRNA-202 safeguards meiotic progression by preventing premature SEPARASE-mediated REC8 cleavage.
results indicate that cyclin B2/CDK1 is also responsible for separase inhibition via inhibitory phosphorylation to regulate chromosome separation in oocyte meiosis, which may not occur in other cell types.
Title: The cyclin B2/CDK1 complex inhibits separase activity in mouse oocyte meiosis I.
Thus, tethering of separase to DSBs and confined cohesin cleavage promote DSB repair in G2 cells. Importantly, this conserved interphase function of separase protects mammalian cells from oncogenic transformation.

Separase-overexpressing mammary cells are not only susceptible to chromosomal missegregation-induced aneuploidy but also other genetic instabilities
Title: MMTV-Espl1 transgenic mice develop aneuploid, estrogen receptor alpha (ERα)-positive mammary adenocarcinomas.
With the continual loss of cohesins from chromosomes that occurs throughout the natural reproductive lifespan, tight regulation of separase in oocytes may be particularly important to maintain cohesion and prevent aneuploidy.

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.
