  • A Conserved Domain in the Scc3 Subunit of Cohesin Mediates

    Mar 06, 2015 · Cohesin is also important for chromosome condensation, DNA repair, and gene expression. Cohesin is comprised of Scc3, Mcd1, Smc1, and Smc3. Scc3 also binds Pds5 and Wpl1, cohesin-associated proteins that regulate cohesin function, and to the Scc2/4 cohesin loader. We mutagenized SCC3 to elucidate its role in cohesin function.

    Apr 20, 2011 · Scc2 localizes to meiotic chromosomes, and its binding sites highly overlap with the cohesin-associated regions. To investigate chromosome association of Scc2 during yeast meiosis, we localized Scc2 and Rec8 on surface-spread nuclei by indirect immunofluorescence ().At pachytene, where homologues are paired and synapsed, Scc2, like Rec8, was localized along the length of the …

  • Cohesin loading and sliding | Journal of Cell Science

    Cohesin is a crucial component of chromosomal stability (Guacci et al., 1997; Losada et al., 1998; Michaelis et al., 1997).It consists of at least six subunits, the structural maintenance of chromosome (Smc) proteins Smc1 and Smc3, sister chromatid cohesion protein 1 (Scc1) (also known as Mcd1 or Rad21), Scc3 (also known as SA or stromalin), Pds5 and Wapl, which are all evolutionarily conserved.

    Furthermore, the Mis4 Scc2 loader was found to form a tertiary complex with cohesin on DNA, where its DNA binding activity facilitates the initial DNA binding of cohesin. In fission yeast cells, residues that support Mis4 Scc2 -DNA interaction are important for chromosomal cohesin loading and for cell viability.

    Jul 15, 2015 · Mutation of SCC2 was associated with defects in the production of ribosomal RNA, ribosome assembly, and splicing. While the scc2 mutant does not have a general defect in protein synthesis, it shows increased frameshifting and reduced cap-independent translation. These findings suggest Scc2 normally promotes a gene expression program that
