"DCTPP1" - dCTP pyrophosphatase 1 in Homo sapiens
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 Size
small protein node
small nodes:
protein of unknown 3D structure
large protein node
large nodes:
some 3D structure is known or predicted
Node Color
colored protein node
colored nodes:
query proteins and first shell of interactors
non-colored protein node
white nodes:
second shell of interactors
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
database edge
from curated databases
experiment edge
experimentally determined
Predicted Interactions
neighborhood edge
gene neighborhood
fusion edge
gene fusions
cooccurrence edge
gene co-occurrence
Others
textmining edge
textmining
coexpression edge
co-expression
homology edge
protein homology

DCTPP1dCTP pyrophosphatase 1; Hydrolyzes deoxynucleoside triphosphates (dNTPs) to the corresponding nucleoside monophosphates. Has a strong preference for modified dCTP. Activity is highest with 5-iodo-dCTP, followed by 5-bromo-dCTP, unmodified dCTP, 5-methyl-dCTP and 5-chloro-dCTP. Hydrolyzes 2-chloro-dATP and 2-hydroxy-dATP with lower efficiency, and has even lower activity with unmodified dATP, dTTP and dUTP (in vitro). Does not hydrolyze ATP, UTP, ITP, GTP, dADP, dCDP or dGTP. May protect DNA or RNA against the incorporation of non- canonical nucleotide triphosphates. May protect cells a [...] (170 aa)    
Predicted Functional Partners:
DCTD
dCMP deaminase; Supplies the nucleotide substrate for thymidylate synthetase (189 aa)
      score_image   score_image score_image   0.931
POLD1
polymerase (DNA directed), delta 1, catalytic subunit; Possesses two enzymatic activities- DNA synthesis (polymerase) and an exonucleolytic activity that degrades single stranded DNA in the 3’- to 5’-direction. Required with its accessory proteins (proliferating cell nuclear antigen (PCNA) and replication factor C (RFC) or activator 1) for leading strand synthesis. Also involved in completing Okazaki fragments initiated by the DNA polymerase alpha/primase complex (1107 aa)

POLD3
polymerase (DNA-directed), delta 3, accessory subunit; Required for optimal DNA polymerase delta activity (466 aa)
      score_image   score_image     0.905
PRIM1
primase, DNA, polypeptide 1 (49kDa); DNA primase is the polymerase that synthesizes small RNA primers for the Okazaki fragments made during discontinuous DNA replication (420 aa)
      score_image   score_image     0.903
POLA2
polymerase (DNA directed), alpha 2, accessory subunit; May play an essential role at the early stage of chromosomal DNA replication by coupling the polymerase alpha/primase complex to the cellular replication machinery (By similarity) (598 aa)

POLE
polymerase (DNA directed), epsilon, catalytic subunit; Participates in DNA repair and in chromosomal DNA replication (2286 aa)
      score_image   score_image     0.903
POLA1
polymerase (DNA directed), alpha 1, catalytic subunit; Plays an essential role in the initiation of DNA replication. During the S phase of the cell cycle, the DNA polymerase alpha complex (composed of a catalytic subunit POLA1/p180, a regulatory subunit POLA2/p70 and two primase subunits PRIM1/p49 and PRIM2/p58) is recruited to DNA at the replicative forks via direct interactions with MCM10 and WDHD1. The primase subunit of the polymerase alpha complex initiates DNA synthesis by oligomerising short RNA primers on both leading and lagging strands. These primers are initially extended by [...] (1462 aa)

CMPK2
cytidine monophosphate (UMP-CMP) kinase 2, mitochondrial; May participate in dUTP and dCTP synthesis in mitochondria. Is able to phosphorylate dUMP, dCMP, CMP, UMP and monophosphates of the pyrimidine nucleoside analogs ddC, dFdC, araC, BVDU and FdUrd with ATP as phosphate donor. Efficacy is highest for dUMP followed by dCMP; CMP and UMP are poor substrates. May be involved in mtDNA depletion caused by long term treatment with ddC or other pyrimidine analogs (449 aa)

NME4
NME/NM23 nucleoside diphosphate kinase 4; Major role in the synthesis of nucleoside triphosphates other than ATP (By similarity) (187 aa)
      score_image   score_image     0.902
DCK
deoxycytidine kinase; Required for the phosphorylation of the deoxyribonucleosides deoxycytidine (dC), deoxyguanosine (dG) and deoxyadenosine (dA). Has broad substrate specificity, and does not display selectivity based on the chirality of the substrate. It is also an essential enzyme for the phosphorylation of numerous nucleoside analogs widely employed as antiviral and chemotherapeutic agents (260 aa)
