ASF1

CIA1, nucleosome assembly factor ASF1, L000000126, YJL115W
Nucleosome assembly factor; involved in chromatin assembly and disassembly, anti-silencing protein that causes derepression of silent loci when overexpressed; plays a role in regulating Ty1 transposition; relocalizes to the cytosol in response to hypoxia
Saccharomyces cerevisiae (S288c)

Phenotypic Enhancement

A genetic interaction is inferred when mutation or overexpression of one gene results in enhancement of any phenotype (other than lethality/growth defect) associated with mutation or over expression of another gene.

Maintenance of Heterochromatin Boundary and Nucleosome Composition at Promoters by the Asf1 Histone Chaperone and SWR1-C Chromatin Remodeler in Saccharomyces cerevisiae.

Lu PY, Kobor MS

Chromatin remodeling complexes cooperate to regulate gene promoters and to define chromatin neighborhoods. Here, we identified genetic and functional connections between two silencing-related chromatin factors in the maintenance of native heterochromatic structures and nucleosome composition at promoters. Building on a previously reported link between the histone chaperone Asf1 and the Yaf9 subunit of the SWR1-C chromatin remodeler, we found that ... [more]

Throughput

  • Low Throughput

Ontology Terms

  • phenotype: rna accumulation (APO:0000224)
  • phenotype: silencing (APO:0000046)
  • phenotype: cold sensitivity (APO:0000148)
  • phenotype: resistance to chemicals (APO:0000087)
