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

SlbpHistone RNA hairpin-binding protein; Stem-loop binding protein (Slbp) encodes a protein that plays an essential role in 3' end processing of histone pre-mRNAs into mature histone mRNAs by recruiting the product of snRNA:U7 to the pre-mRNA. (276 aa)    
Predicted Functional Partners:
Lsm11
FI05704p; Lsm11 (Lsm11) encodes one of the seven proteins that form a heptameric Sm ring in the U7 snRNP, which is a key factor involved in 3' end processing of histone pre-mRNAs. It interacts with the product of FLASH. The two interacting proteins form a biochemical platform that recruits a number of polyadenylation subunits to the U7 snRNP, including the products of Sym, Cpsf100, Cpsf73 and CstF64.

Lsm10
Lsm10 (Lsm10) encodes a core component of the U7 snRNP complex, which functions in 3' end processing of the non-polyadenylated, replication-dependent histone mRNAs. The product of Lsm10 is part of the heptameric Sm ring complex that binds directly to U7 snRNA. It replaces the protein encoded by SmD1 in the canonical heptameric Sm protein ring that binds spliceosomal snRNAs.

Sym
Symplekin (Sym) encodes a large protein that contains many protein interaction sites, and acts as a scaffold for protein complexes in the nucleus. It functions in RNA 3' end formation for both polyadenyated mRNAs and non-polyadenylated histone mRNAs. In some cells it also localizes to the cell cortex, especially the tricellular junctions of some epithelia.

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 [...]
   
 0.929
Cpsf73
Cleavage 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 [...]

Upf1
Regulator of nonsense transcripts 1 homolog; RNA-dependent helicase and ATPase required for nonsense- mediated decay (NMD) of mRNAs containing premature stop codons. Is recruited to mRNAs upon translation termination and undergoes a cycle of phosphorylation and dephosphorylation; its phosphorylation appears to be a key step in NMD. The formation of an Upf1-Upf2-Upf3 surveillance complex is believed to activate NMD (By similarity).

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 [...]

CG13124
LP20791p; RNA binding; translation activator activity. It is involved in the biological process described with: regulation of translational initiation.

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.
