SMC3

cohesin subunit SMC3, L000003992, YJL074C
Subunit of the multiprotein cohesin complex; required for sister chromatid cohesion in mitotic cells; also required, with Rec8p, for cohesion and recombination during meiosis; phylogenetically conserved SMC chromosomal ATPase family member
Saccharomyces cerevisiae (S288c)
PREY

HMO1

HSM2, L000003234, YDR174W
Chromatin associated high mobility group (HMG) family member; involved in compacting, bending, bridging and looping DNA; rDNA-binding component that regulates transcription from RNA polymerase I promoters; regulates start site selection of ribosomal protein genes via RNA polymerase II promoters; role in genome maintenance; associates with a 5'-3' DNA helicase and Fpr1p, a prolyl isomerase; relocalizes to the cytosol in response to hypoxia
Saccharomyces cerevisiae (S288c)

Co-purification

An interaction is inferred from the identification of two or more protein subunits in a purified protein complex, as obtained by classical biochemical fractionation or affinity purification and one or more additional fractionation steps.

Histone tail-independent chromatin binding activity of recombinant cohesin holocomplex.

Cohesin, an SMC (structural maintenance of chromosomes) protein-containing complex, governs several important aspects of chromatin dynamics, including the essential chromosomal process of sister chromatid cohesion. The exact mechanism by which cohesin achieves the bridging of sister chromatids is not known. To elucidate this mechanism, we reconstituted a recombinant cohesin complex and investigated its binding to DNA fragments corresponding to natural ... [more]

Mutations/deletions in separate genes, each of which alone causes a minimal phenotype, but when combined in the same cell results in a more severe fitness defect or lethality under a given condition. This term is reserved for high or low throughput studies with scores.
