Required for the maintenance of meiotic cohesion, but not, or only to a minor extent, for its establishment. Contributes to axial element (AE) formation and the organization of chromatin loops along the AE. Plays a key role in synapsis, recombination and chromosome movements. The cohesin complex is required for the cohesion of sister chromatids after DNA replication. The cohesin complex apparently forms a large proteinaceous ring within which sister chromatids can be trapped. At anaphase, the complex is cleaved and dissociates from chromatin, allowing sister chromatids to segregate. The meiosis-specific cohesin complex probably replaces mitosis specific cohesin complex when it dissociates from chromatin during prophase I (By similarity). {ECO:0000250}. |SMC hinge| |SMC N| |nuclear meiotic cohesin complex| |meiotic cohesin complex| |lateral element| |sister chromatid cohesion| |chromosome, centromeric region| |sister chromatid segregation| |nuclear chromosome segregation| |meiotic cell cycle| |chromosome segregation| |cell cycle process| |chromosome organization| |cell cycle| |reproductive process| |reproduction| |DNA binding| |ATP binding| \\ === CRISPR Data === ^Screen^Score^ |[[:results:exp438|NN-Diethyl-meta-toluamide 500μM R08 exp438]]|1.72| |[[:results:exp12|Chloramphenicol 2μM R00 exp12]]|1.73| |[[:results:exp453|B02 10μM R08 exp453]]|2.12| No correlation found to any other genes in chemogenomics.
