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:
a 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 to each other.
Known Interactions
from curated databases
experimentally determined
Predicted Interactions
gene neighborhood
gene fusions
gene co-occurrence
Others
textmining
co-expression
protein homology

Orc2Origin recognition complex subunit 2; Component of the origin recognition complex (ORC) that binds origins of replication. DNA-binding is ATP-dependent, however specific DNA sequences that define origins of replication have not been identified so far. ORC is required to assemble the pre-replication complex necessary to initiate DNA replication. (618 aa)    
Predicted Functional Partners:
Mcm3
DNA replication licensing factor Mcm3; Acts as component of the Mcm2-7 complex (Mcm 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 box of the adjacent subunit. The six ATPase active sites, however, are likely to contribut [...]

Orc4
Origin recognition complex subunit 4 (Orc4) encodes is a subunit of the hetero-hexameric origin recognition complex (ORC). The ORC binds to origins of DNA replication and scaffolds assembly of a pre-replicative complex, which is required for the initiation of DNA replication. At other loci, the ORC is required for heterochromatin formation.

Cdc6
Cell division control protein; Cdc6 (Cdc6) encodes an essential component of the pre-Replication complex (preRC) together with the origin recognition complex, the product of dup and MCM2-7 proteins. The preRC is present at all chromosomal origins of replication and is required for the initiation of DNA replication. The product of Cdc6 also functions in the co-ordination of DNA replication with mitosis, and may contribute to apoptosis and transcription; Belongs to the CDC6/cdc18 family.

Orc5
Origin recognition complex subunit 5; Component of the origin recognition complex (ORC) that binds origins of replication. DNA-binding is ATP-dependent, however specific DNA sequences that define origins of replication have not been identified so far. ORC is required to assemble the pre-replication complex necessary to initiate DNA replication (By similarity).

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 box of the adjacent subunit. The six ATPase active sites, however, are likely to contribute differential [...]

dup
Double parked (dup) encodes an essential protein for the initiation of DNA replication due to its recruitment of the MCM helicase to replication origins.

Orc3
Origin recognition complex subunit 3 (Orc3) encodes a subunit of the origin recognition complex. It is involved in DNA replication initiation and border follicle cell migration regulation.

Orc6
Origin recognition complex subunit 6; Component of the origin recognition complex (ORC) that binds origins of replication. DNA-binding is ATP-dependent, however specific DNA sequences that define origins of replication have not been identified so far. ORC is required to assemble the pre-replication complex necessary to initiate DNA replication (By similarity).

Orc1
Origin recognition complex subunit 1 (Orc1) encodes the largest subunit of the origin recognition complex (ORC), which is essential for the initiation of DNA replication in eukaryotic cells. The ATPase activity of the product of Orc1 is critical for the formation and function of the pre-replicative complex. The regulated degradation of the product of Orc1 by ubiquitin-mediated proteolysis after initiation of DNA replication helps to prevent re-replication.
