STRINGSTRING
SLD2 protein (Saccharomyces cerevisiae) - STRING interaction network
"SLD2" - Single-stranded DNA origin-binding and annealing protein in Saccharomyces cerevisiae
Nodes:
Network nodes represent proteins
splice isoforms or post-translational modifications are collapsed, i.e. each node represents all the proteins produced by a single, protein-coding gene locus.
Node Color
colored nodes:
query proteins and first shell of interactors
white nodes:
second shell of interactors
Node Content
empty nodes:
proteins of unknown 3D structure
filled nodes:
some 3D structure is known or predicted
Edges:
Edges represent protein-protein associations
associations are meant to be specific and meaningful, i.e. proteins jointly contribute to a shared function; this does not necessarily mean they are physically binding each other.
Known Interactions
from curated databases
experimentally determined
Predicted Interactions
gene neighborhood
gene fusions
gene co-occurrence
Others
textmining
co-expression
protein homology

Required at S-phase checkpoint. Also required for the proper activation of RAD53 in response to DNA damage and replication blocks (453 aa)    
Predicted Functional Partners:
DPB11
Replication initiation protein that loads DNA pol epsilon onto pre-replication complexes at origins; checkpoint sensor recruited to stalled replication forks by the checkpoint clamp complex where it activates Mec1p; ortholog of human TopBP1; Has a role in the initiation of DNA replication. Required at S-phase checkpoint. Required for the association of PSF1 with origins. Also required for the proper activation of RAD53 in response to DNA damage and replication blocks. Multicopy suppressor of DPB2 mutation. Overexpression restores the growth defect conferred by POL2 mutation (764 aa)

CDC45
DNA replication initiation factor; recruited to MCM pre-RC complexes at replication origins; promotes release of MCM from Mcm10p, recruits elongation machinery; mutants in human homolog may cause velocardiofacial and DiGeorge syndromes; Required for initiation of chromosomal DNA replication. Acts at the origin of replication. Also has a role in minichromosome maintenance (650 aa)

DBF4
Regulatory subunit of Cdc7p-Dbf4p kinase complex, required for Cdc7p kinase activity and initiation of DNA replication; phosphorylates the Mcm2-7 family of proteins; cell cycle regulated; Regulatory subunit of the CDC7-DBF4 kinase, also called DBF4-dependent kinase (DDK), which is involved in cell cycle regulation of premitotic and premeiotic chromosome replication and in chromosome segregation. DDK plays an essential role in initiating DNA replication at replication origins by phosphorylating the MCM2 and MCM4 subunits of the MCM2-7 helicase complex. DBF4 recruits the catalytic subuni [...] (704 aa)

MCM2
Protein involved in DNA replication; component of the Mcm2-7 hexameric complex that binds chromatin as a part of the pre-replicative complex; Acts as component of the MCM2-7 complex (MCM complex) which is the putative replicative helicase essential for ’once per cell cycle’ DNA replication initiation and elongation in eukaryotic cells. The active ATPase sites in the MCM2-7 ring are formed through the interaction surfaces of two neighboring subunits such that a critical structure of a conserved arginine finger motif is provided in trans relative to the ATP-binding site of the Walker A b [...] (868 aa)
