MSI1/YBR195C Summary Help

Standard Name MSI1 1
Systematic Name YBR195C
Alias CAC3
Feature Type ORF, Verified
Description Subunit of chromatin assembly factor I (CAF-1); chromatin assembly by CAF-1 affects multiple processes including silencing at telomeres, mating type loci, and rDNA; maintenance of kinetochore structure; deactivation of DNA damage checkpoint after DNA repair; chromatin dynamics during transcription; and repression of divergent noncoding transcription; Msi1p localizes to nucleus and cytoplasm and independently regulates the RAS/cAMP pathway via sequestration of Npr1p kinase (2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12)
Name Description Multicopy Suppressor of IRA1 13
