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
Your Input:
Dcr-2Dicer-2, isoform A; Dicer-2 (Dcr-2) encodes a member of the RNase III family of double-stranded RNA-specific endonucleases. It acts in the RNAi pathway by cutting long dsRNA into siRNAs. It helps defend flies against viral infection, particularly RNA viruses. It also processes long, partially double-stranded endogenous transcripts (hairpin RNAs) into endo-siRNAs. (1722 aa)
Cpsf73Cleavage and polyadenylation specificity factor 73; Component of the cleavage and polyadenylation specificity factor (CPSF) complex that plays a key role in pre-mRNA 3'-end formation, recognizing the AAUAAA signal sequence and interacting with poly(A) polymerase and other factors to bring about cleavage and poly(A) addition. Has endonuclease activity and functions as mRNA 3'- end-processing endonuclease. Required for the cotranscriptional processing of 3'-ends of polyadenylated and histone pre-mRNA. Belongs to the metallo-beta-lactamase superfamily. RNA- metabolizing metallo-beta-lacta [...] (684 aa)
CstF64Cleavage 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. (419 aa)
Rpb3RNA polymerase II 33kD subunit; DNA-directed 5'-3' RNA polymerase activity; RNA polymerase II activity; protein dimerization activity; DNA binding. It is involved in the biological process described with: transcription by RNA polymerase II; cellular response to heat. (275 aa)
piwiProtein piwi; Acts via the piwi-interacting RNA (piRNA) metabolic process, which mediates the repression of transposable elements during meiosis by forming complexes composed of piRNAs and Piwi proteins and governs the methylation and subsequent repression of transposons. Directly binds piRNAs, a class of 24 to 30 nucleotide RNAs that are generated by a Dicer-independent mechanism and are primarily derived from transposons and other repeated sequence elements. In ovarian somatic cells, mediates silencing of transposable elements at the transcriptional level in a mael-dependent manner. [...] (843 aa)
Su(var)205Heterochromatin protein 1; Structural component of heterochromatin, involved in gene repression and the modification of position-effect-variegation. Recognizes and binds histone H3 tails methylated at 'Lys-9', leading to epigenetic repression. (206 aa)
Fip1Factor interacting with poly(A) polymerase 1; Myosin binding. It is involved in the biological process described with: mRNA polyadenylation; positive regulation of transcription by RNA polymerase II; pre-mRNA cleavage required for polyadenylation; mRNA 3'-end processing by stem-loop binding and cleavage. (701 aa)
Rai1Decapping nuclease DXO homolog; 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'-pyrophosphohydrolase activity by hydrolyzing the 5' end triphosphate to release pyrophosphates (By similarity). Belongs to the DXO/Dom3Z family. (375 aa)
ClpCleavage and polyadenylation specificity factor subunit 4; Component of the cleavage and polyadenylation specificity factor (CPSF) complex that plays a key role in pre-mRNA 3'-end formation, recognizing the AAUAAA signal sequence and interacting with poly(A) polymerase and other factors to bring about cleavage and poly(A) addition. Has endonuclease activity. Binds RNA polymers with a preference for G- and/or C-rich clusters. Binds single-stranded DNA non-specifically. (296 aa)
nonCSerine/threonine-protein kinase Smg1; Serine/threonine protein kinase involved in mRNA surveillance. Recognizes the substrate consensus sequence [ST]-Q. Involved in nonsense-mediated decay (NMD) of mRNAs containing premature stop codons, probably by phosphorylating Upf1. (3218 aa)
G9aG9a, isoform B; G9a (G9a) encodes a histone-lysine methyltransferase involved in epigenetic regulation. It contributes to multiple processes including gene expression, dendrite morphogenesis, larval locomotory behavior as well as short and long-term memory. (1657 aa)
TfIISTranscription elongation factor S-II; Necessary for efficient RNA polymerase II transcription elongation past template-encoded arresting sites. The arresting sites in DNA have the property of trapping a certain fraction of elongating RNA polymerases that pass through, resulting in locked ternary complexes. Cleavage of the nascent transcript by S-II allows the resumption of elongation from the new 3'-terminus. (313 aa)
elavProtein elav; Required for the proper development and maintenance of neurons presumably by affecting RNA metabolism. Belongs to the RRM elav family. (483 aa)
Pcf11Protein 1 of cleavage and polyadenylation factor 1 (Pcf11) encodes an RNA binding protein involved in RNA splicing regulation. (1953 aa)
Spn43AbSerpin 43Ab; Serine-type endopeptidase inhibitor activity. It is involved in the biological process described with: negative regulation of endopeptidase activity; multicellular organism reproduction; Belongs to the serpin family. (393 aa)
droshaRibonuclease; Drosha (drosha) encodes a protein that contributes to miRNA processing. It is involved in salivary gland histolysis and oocyte development. (1327 aa)
Ser7GH14088p; Serine-type endopeptidase activity; serine-type peptidase activity. It is involved in the biological process described with: proteolysis; Belongs to the peptidase S1 family. (397 aa)
Cdk9Positive transcription elongation factor b small subunit; Cyclin-dependent kinase 9 (Cdk9) encodes a cyclin dependent kinase that along with the product of CycT forms the positive transcription elongation factor, which is involved in RNA polymerase II elongation control. (404 aa)

fusRNA-binding protein fusilli; mRNA splicing factor that regulates alternative splicing od specific genes. Has a maternal role in embryonic dorsal-ventral patterning; such role is probably indirect and due to its function as mRNA splicing factor regulator. (967 aa)
