Phosphorylation of canonical motifs in Sld2 does not play a direct role in complex formation with Dpb11, but rather regulates phosphorylation of another residue, Thr84.

Preferred Names: Sld2p

NP_012814.1

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
