SLD2/YKL108W Summary Help

Standard Name SLD2 1
Systematic Name YKL108W
Alias DRC1 2
Feature Type ORF, Verified
Description Single-stranded DNA origin-binding and annealing protein; required for initiation of DNA replication; phosphorylated in S phase by cyclin-dependent kinases (Cdks), promoting origin binding, DNA replication and Dpb11p complex formation; component of the preloading complex; binds the Mcm2-7p complex to prevent inappropriate Mcm2-7p interaction with the GINS complex in G1; required for S phase checkpoint; relative distribution to the nucleus increases upon DNA replication stress (2, 3, 4, 5, 6, 7, 8, 9, 10, 11)
Name Description Synthetically Lethal with Dpb11-1 1
