ECO1/YFR027W Summary Help

Standard Name ECO1 1
Systematic Name YFR027W
Alias CTF7 2
Feature Type ORF, Verified
Description Acetyltransferase; required for establishment of sister chromatid cohesion; acetylates Mps3p to regulate nuclear organization; modifies Smc3p at replication forks and Mcd1p in response to dsDNA breaks; phosphorylated by three kinases (Cdc28p, Cdc7p, Mck1p) to generate pair of phosphates spaced precisely for recognition by ubiquitin ligase SCF-Cdc4; mutations in human homolog ESCO2 cause Roberts syndrome; relative distribution to nucleus increases upon DNA replication stress (1, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15)
