STRINGSTRING
STRING protein interaction network
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

Pabp2Polyadenylate-binding protein 2; Involved in the 3'-end formation of mRNA precursors (pre- mRNA) by the addition of a poly(A) tail of 200-250 nt to the upstream cleavage product. Stimulates poly(A) polymerase (PAPOLA) conferring processivity on the poly(A) tail elongation reaction and controls also the poly(A) tail length (By similarity). Increases the affinity of poly(A) polymerase for RNA (By similarity). Binds to poly(A) and to poly(G) with high affinity. May protect the poly(A) tail from degradation (By similarity). Plays a role in the positive regulation of alpha-1,3 fucosylation, [...] (224 aa)    
Predicted Functional Partners:
hrg
Hiiragi, isoform D; Hiiragi (hrg) encodes the canonical poly(A) polymerase required for the nuclear poly(A) tail synthesis at the mRNA 3'-end. hrg product is also involved in cytoplasmic polyadenylation of specific mRNAs during early to mid-oogenesis, through its interaction with the CPEB (cytoplasmic polyadenylation element binding) protein encoded by orb.

CstF64
Cleavage stimulation factor 64 kD subunit (CstF64) encodes an RNA-binding protein that is part of the cleavage stimulation factor (CstF) complex. As part of the CstF complex, it interacts with the polyadenylation protein encoded bysu(f). The product of CstF64 is necessary for the cleavage and polyadenylation of most mRNAs and for 3' end processing of mRNAs that encode the replication-dependent histones.

pAbp
Polyadenylate-binding protein; Binds the poly(A) tail of mRNA. Since it interacts with the cap-associating translation initiation factor eIF4G, it is likely that it functions by linking Atx2 to the cap-binding complex. Forms a complex with tyf and Atx2 which functions in adult circadian pacemaker neurons to sustain circadian rhythms likely by switching between activator and repressor modes of post-transcriptional regulation via interaction with Lsm12a or me31B, respectively. The activator complex (Atx2-tyf activator complex) activates the TYF-dependent translation of per to maintain 24 [...]

Cbp20
Nuclear cap-binding protein subunit 2; Component of the cap-binding complex (CBC), which binds co- transcriptionally to the 5' cap of pre-mRNAs and is involved in various processes such as pre-mRNA splicing and RNA-mediated gene silencing (RNAi). The CBC complex is involved in miRNA-mediated RNA interference via its interaction with Ars2 and is required for primary microRNAs (miRNAs) processing. Also involved in innate immunity via the short interfering RNAs (siRNAs) processing machinery by restricting the viral RNA production. In the CBC complex, Cbp20 recognizes and binds capped RNAs [...]

SF2
Splicing factor 2 (SF2) encodes a protein involved in alternative mRNA splicing, RNA export from the nucleus and the regulation of the RNA metabolism.
   
 0.909
Cbp80
Nuclear cap-binding protein subunit 1; Component of the cap-binding complex (CBC), which binds cotranscriptionally to the 5'-cap of pre-mRNAs and is involved in various processes such as pre-mRNA splicing and RNA-mediated gene silencing (RNAi). The CBC complex is involved in miRNA-mediated RNA interference via its interaction with Ars2 and is required for primary microRNAs (miRNAs) processing. Also involved in innate immunity via the short interfering RNAs (siRNAs) processing machinery by restricting the viral RNA production. In the CBC complex, Cbp80 does not bind directly capped RNAs [...]

mle
Dosage compensation regulator; Required in males for dosage compensation of X chromosome linked genes. Mle, msl-1 and msl-3 are colocalized on X chromosome. Each of the msl proteins requires all the other msls for wild-type X- chromosome binding. Probably unwinds double-stranded DNA and RNA in a 3' to 5' direction; Belongs to the DEAD box helicase family. DEAH subfamily.

ZC3H3
Zinc finger CCCH domain-containing protein 3; Required for the export of polyadenylated mRNAs from the nucleu; binds to polyadenylated mRNA, and is involved in the regulation of mRNA polyadenylation.
    
 
 0.889
U2af50
U2 small nuclear riboprotein auxiliary factor 50 (U2af50) encodes the large subunit of the heterodimeric complex U2AF. U2AF binds to the intron pyrimidine tract between the branchpoint and the 3' splice site and targets U2 snRNP to the branch site early in spliceosome assembly.

Srp54
LD29830p; Srp54 (Srp54) encodes a protein that regulates mRNA alternative splicing, the processing of the mRNA 3'-end and the selection of the transcriptional start site.
