Target Background

Function

Component of cohesin complex, a complex 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 MCD1/SCC1 subunit of the complex is cleaved and dissociates from chromatin, allowing sister chromatids to segregate. The cohesin complex may also play a role in spindle pole assembly during mitosis.

Gene References into Functions

Scc3 C-terminal domain binds Scc1 and promotes de-acetylation of Smc3 upon Scc1 cleavage. PMID: 25171859
expression of 33 genes is affected by the presence of the mutated Irr1-1p and identify those genes. This supports the suggested role of Irr1p in the regulation of transcription. Irr1p may interact with elements of transcriptional coactivator Mediator PMID: 23730682
The expression of MCD1 was not subject to Scc3 regulation in vegetative cells. Scc3 and Smc1 are both required for the production of the meiosis-specific subunit Rec8. PMID: 21270391
IRR1-1 mutation in heterozygous state may influence the cell wall integrity and indicates a possible link between mechanisms regulating the cell wall biosynthesis, nuclear migration and chromosome segregation. PMID: 17229992
The F658G substitutionin Irr1 was found to induce marked changes in the general shape of the predicted protein which retains its ability to interact with Scc1p, another component of the cohesin complex. PMID: 18617290

Subcellular Location

Nucleus. Chromosome. Chromosome, centromere. Note=Associates with chromatin. Before prophase it is scattered along chromosome arms. During prophase, most of cohesin complexes dissociate from chromatin except at centromeres, where cohesin complexes remain. At anaphase, the MCD1 subunit of the cohesin complex is cleaved, leading to the dissociation of the complex from chromosomes, allowing chromosome separation.
