STRINGSTRING
DXO1 protein (Saccharomyces cerevisiae) - STRING interaction network
"DXO1" - Putative protein of unknown function 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

DXO1Putative protein of unknown function; Ribonuclease that specifically degrades pre-mRNAs with a defective 5’ end cap and is part of a pre-mRNA capping quality control. Has decapping and 5’-3’ exonuclease activities. Has decapping activity toward incomplete 5’ end cap mRNAs such as unmethylated 5’ end-capped RNA to release GpppN and 5’ end monophosphate RNA. The 5’ end monophosphate RNA is then degraded by the 5’-3’ exoribonuclease activity, enabling this enzyme to decap and degrade incompletely capped mRNAs (442 aa)    
Predicted Functional Partners:
RAI1
Nuclear protein with decapping endonuclease activity targeted toward mRNAs with unmethylated 7-methylguanosine cap structures; binds to and stabilizes the exoribonuclease Rat1p; required for pre-rRNA processing; homologous to human DOM3Z; Ribonuclease that specifically degrades pre-mRNAs with a defective 5’ end cap and is part of a pre-mRNA capping quality control. Has decapping and pyrophosphohydrolase activities. Has decapping activity toward incomplete 5’ end cap mRNAs such as unmethylated 5’ end-capped RNA to release GpppN and 5’ end monophosphate RNA. Also possesses RNA 5’-pyropho [...] (387 aa)

DCS1
Non-essential hydrolase involved in mRNA decapping, may function in a feedback mechanism to regulate deadenylation, contains pyrophosphatase activity and a HIT (histidine triad) motif; interacts with neutral trehalase Nth1p; Decapping scavenger enzyme that catalyzes the cleavage of a residual cap structure following the degradation of mRNAs by the 3’->5’ exosome-mediated mRNA decay pathway. Hydrolyzes cap analog structures like 7-methylguanosine nucleoside triphosphate (m7GpppG) and tri-methyl guanosine nucleoside triphosphate (m3(2,2,7)GpppG) with up to 10 nucleotide substrates (small [...] (350 aa)

PRP5
RNA helicase in the DEAD-box family, necessary for prespliceosome formation, bridges U1 and U2 snRNPs and enables stable U2 snRNP association with intron RNA; ATP-dependent RNA helicase involved spliceosome assembly and in nuclear splicing. Catalyzes an ATP-dependent conformational change of U2 snRNP. Bridges U1 and U2 snRNPs and enables stable U2 snRNP association with intron RNA (849 aa)

RAT1
Nuclear 5’ to 3’ single-stranded RNA exonuclease, involved in RNA metabolism, including rRNA and snRNA processing as well as poly (A+) dependent and independent mRNA transcription termination; Possesses 5’->3’ exoribonuclease activity. Required for the processing of nuclear mRNA, rRNA and small nucleolar RNA (snoRNA) precursors. May promote termination of transcription by RNA polymerase II via the recruitment of 3’-end processing factors to the poly(A) site and by the degradation of nascent RNA downstream of the poly(A) site (1006 aa)
