STRING protein interaction network
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 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
protein homology
Your Input:
Gene Fusion
nudIPyrimidine deoxynucleotide diphosphatase nudi; Catalyzes the hydrolysis of nucleoside triphosphates, with a preference for pyrimidine deoxynucleoside triphosphates (dUTP, dTTP and dCTP) (141 aa)    
Predicted Functional Partners:
Nucleoside-diphosphate kinase; Major role in the synthesis of nucleoside triphosphates other than ATP. The ATP gamma phosphate is transferred to the NDP beta phosphate via a ping-pong mechanism, using a phosphorylated active-site intermediate
Thymidylate synthetase; Catalyzes the reductive methylation of 2'-deoxyuridine-5'- monophosphate (dUMP) to 2'-deoxythymidine-5'-monophosphate (dTMP) while utilizing 5,10-methylenetetrahydrofolate (mTHF) as the methyl donor and reductant in the reaction, yielding dihydrofolate (DHF) as a by-product . This enzymatic reaction provides an intracellular de novo source of dTMP, an essential precursor for DNA biosynthesis. This protein also binds to its mRNA thus repressing its own translation
Deoxycytidine triphosphate deaminase; Catalyzes the deamination of dCTP to dUTP
Ribonucleoside-triphosphate reductase (formate); Catalyzes the conversion of ribonucleotides into deoxyribonucleotides, which are required for DNA synthesis and repair
Bifunctional thiamine pyrimidine pyrophosphate hydrolase and thiamine pyrophosphate hydrolase; Catalyzes the hydrolysis of 4-amino-2-methyl-5- hydroxymethylpyrimidine pyrophosphate (HMP-PP) to 4-amino-2-methyl-5- hydroxymethylpyrimidine phosphate (HMP-P), and hydrolysis of thiamine pyrophosphate (TPP) to thiamine monophosphate (TMP). Can hydrolyze other substrates such as MeO-HMP-PP, CF(3)-HMP-PP and MeO-TPP. Is also a non-specific nucleoside tri- and diphosphatase that releases inorganic orthophosphate
Dgtp-preferring nucleoside triphosphate pyrophosphohydrolase; Involved in the GO system responsible for removing an oxidatively damaged form of guanine (7,8-dihydro-8-oxoguanine) from DNA and the nucleotide pool. 8-oxo-dGTP is inserted opposite dA and dC residues of template DNA with almost equal efficiency thus leading to A.T to G.C transversions. MutT specifically degrades 8-oxo-dGTP to the monophosphate
Gdp-mannose pyrophosphatase nudk; Nucleoside diphosphate sugar hydrolase that hydrolyzes GDP- mannose as its preferred substrate, yielding GMP and mannose-1- phosphate. Can also hydrolyze the pyrophosphate bond of other sugar nucleotides such as IDP-ribose, GDP-glucose, and to a lesser extent, ADP-ribose, ADP-glucose and UDP-glucose. Shows no activity toward Nudix substrates FAD, CDP-ethanolamine, CDP-choline, NAD(+), diadenosine pentaphosphate, GTP, UTP, ATP, or CTP
Nucleotidase that shows high phosphatase activity toward non- canonical pyrimidine nucleotides and three canonical nucleoside 5'- monophosphates (UMP, dUMP, and dTMP), and very low activity against TDP, IMP, UDP, GMP, dGMP, AMP, dAMP, and 6-phosphogluconate. Appears to function as a house-cleaning nucleotidase in vivo, since the general nucleotidase activity of YjjG allows it to protect cells against non- canonical pyrimidine derivatives such as 5-fluoro-2'-deoxyuridine, 5- fluorouridine, 5-fluoroorotate, 5-fluorouracil, and 5-aza-2'- deoxycytidine, and prevents the incorporation of po [...]
Gmp/imp nucleotidase; Catalyzes the dephosphorylation of different purine nucleotides (GMP and IMP). Also hydrolyzes flavin mononucleotide (FMN)
