UniProtKB - Q12158 (SCC1_YEAST)
Protein
Sister chromatid cohesion protein 1
Gene
MCD1
Organism
Saccharomyces cerevisiae (strain ATCC 204508 / S288c) (Baker's yeast)
Status
Functioni
Cleavable component of the cohesin complex involved in chromosome cohesion during cell cycle. 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 metaphase-anaphase transition, this protein is cleaved by ESP1 and dissociates from chromatin, allowing sister chromatids to segregate.4 Publications
Miscellaneous
Present with 1040 molecules/cell in log phase SD medium.1 Publication

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, it is cleaved by ESP1, leading to the dissociation of the complex from chromosomes, allowing chromosome separation.1 Publication

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