CC -!- FUNCTION: Central component of cohesin, a complex required for
CC chromosome cohesion during the cell cycle. The cohesin complex may form
CC a large proteinaceous ring within which sister chromatids can be
CC trapped. At anaphase, the complex is cleaved and dissociates from
CC chromatin, allowing sister chromatids to segregate. Cohesion is coupled
CC to DNA replication and is involved in DNA repair. The cohesin complex
CC also plays an important role in spindle pole assembly during mitosis
CC and in chromosomes movement (By similarity). {ECO:0000250}.
CC -!- SUBUNIT: Forms a heterodimer with SMC1A or SMC1B in cohesin complexes.
CC Cohesin complexes are composed of the SMC1 (SMC1A or meiosis-specific
CC SMC1B) and SMC3 heterodimer attached via their SMC hinge domain, RAD21
CC which link them, and one STAG protein (STAG1, STAG2 or STAG3), which
CC interacts with RAD21. Also found in meiosis-specific cohesin complexes.
CC Found in a complex with SMC1A, CDCA5 and RAD21, PDS5A/SCC-112 and
CC PDS5B/APRIN. Interacts with MXI1, MXD3 and MXD4. Interacts with NUMA1,
CC and forms a ternary complex with KIF3B and KIFAP3, suggesting a
CC function in tethering the chromosomes to the spindle pole and a
CC function in chromosome movement. Interacts with PDS5A and WAPL;
CC regulated by SMC3 acetylation. Interacts (via SMC hinge domain) with
CC KIAA1328 (via N- and C-terminal domains). Interacts with DDX11, SYCP2,
CC RPGR and STAG3. Found in a cohesin complex with SMC1A, RAD21 and STAG1.
CC The SMC1A-SMC3 heterodimer interacts with the NIPBL-MAU2 heterodimer.
CC Interacts with the NuRD complex component HDAC2; the interaction is
CC direct (By similarity). {ECO:0000250|UniProtKB:O97594,
CC ECO:0000250|UniProtKB:P97690, ECO:0000250|UniProtKB:Q9CW03,
CC ECO:0000250|UniProtKB:Q9UQE7}.
CC -!- SUBCELLULAR LOCATION: Nucleus {ECO:0000250|UniProtKB:Q9CW03}.
CC Chromosome {ECO:0000250|UniProtKB:Q9CW03}. Chromosome, centromere
CC {ECO:0000250|UniProtKB:Q9CW03}. Note=Associates with chromatin. Before
CC prophase it is scattered along chromosome arms. During prophase, most
CC of cohesin complexes dissociate from chromatin probably because of
CC phosphorylation by PLK, except at centromeres, where cohesin complexes
CC remain. At anaphase, the RAD21 subunit of the cohesin complex is
CC cleaved, leading to the dissociation of the complex from chromosomes,
CC allowing chromosome separation (By similarity). The phosphorylated form
CC at Ser-1083 is preferentially associated with unsynapsed chromosomal
CC regions (By similarity). {ECO:0000250|UniProtKB:Q9CW03}.
CC -!- DOMAIN: The flexible SMC hinge domain, which separates the large
CC intramolecular coiled coil regions, allows the heterotypic interaction
CC with the corresponding domain of SMC1A or SMC1B, forming a V-shaped
CC heterodimer. The two heads of the heterodimer are then connected by
CC different ends of the cleavable RAD21 protein, forming a ring structure
CC (By similarity). {ECO:0000250}.
CC -!- PTM: Phosphorylated at Ser-1083 in a SPO11-dependent manner.
CC {ECO:0000250|UniProtKB:Q9CW03}.
CC -!- PTM: Acetylation at Lys-105 and Lys-106 by ESCO1 is important for
CC genome stability and S phase sister chromatid cohesion. Regulated by
CC DSCC1, it is required for processive DNA synthesis, coupling sister
CC chromatid cohesion establishment during S phase to DNA replication (By
CC similarity). Deacetylation by HDAC8, regulates release of the cohesin
CC complex from chromatin (By similarity). {ECO:0000250|UniProtKB:Q9UQE7}.
CC -!- PTM: Ubiquitinated by the DCX(DCAF15) complex, leading to its
CC degradation. {ECO:0000250|UniProtKB:Q9UQE7}.
CC -!- SIMILARITY: Belongs to the SMC family. SMC3 subfamily. {ECO:0000305}.
