Protein

Structural maintenance of chromosomes protein 3

Gene

SMC3

Organism
Saccharomyces cerevisiae (strain ATCC 204508 / S288c) (Baker's yeast)
Status
Reviewed - Annotation score: 5 out of 5- Experimental evidence at protein leveli

Functioni

Involved in chromosome cohesion during cell cycle and in DNA repair. Central component of cohesin complex. 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.

Nucleus. Chromosome
Note: Associates with chromatin. Before prophase it is scattered along chromosome arms. At anaphase, the MCD1 subunit of the cohesin complex is cleaved, leading to the dissociation of the complex from chromosomes, allowing chromosome separation.

Interactioni

Subunit structurei

Cohesin complexes are composed of the SMC1 and SMC3 heterodimer attached via their hinge domain, MCD1/SCC1 which link them, and IRR1/SCC3, which interacts with MCD1. The cohesin complex also interacts with SCC2, which is required for its association with chromosomes.2 Publications

Domaini

The flexible hinge domain, which separates the large intramolecular coiled coil regions, allows the heterotypic interaction with the corresponding domain of SMC1, forming a V-shaped heterodimer. The two heads of the heterodimer are then connected by different ends of the cleavable MCD1 protein, forming a ring structure (By similarity).By similarity
