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

CG1646Pre-mRNA-processing factor 39; Involved in pre-mRNA splicing. (1066 aa)    
Predicted Functional Partners:
snRNP-U1-70K
Small ribonucleoprotein particle U1 subunit 70K (snRNP-U1-70K) encodes a protein component of the U1 snRNP. The U1 snRNP combines with other snRNPs on the pre-mRNA to assemble a spliceosome.

snRNP-U1-C
U1 small nuclear ribonucleoprotein C; Component of the spliceosomal U1 snRNP, which is essential for recognition of the pre-mRNA 5' splice-site and the subsequent assembly of the spliceosome. U1-C is directly involved in initial 5' splice-site recognition for both constitutive and regulated alternative splicing. The interaction with the 5' splice-site seems to precede base-pairing between the pre-mRNA and the U1 snRNA. Stimulates commitment or early (E) complex formation by stabilizing the base pairing of the 5' end of the U1 snRNA and the 5' splice-site region (By similarity). Regulat [...]

CG7564
LD04387p; mRNA binding. It is involved in the biological process described with: mRNA splice site selection; mRNA splicing, via spliceosome.
   
 0.985
Secp43
RE72132p; mRNA binding. It is involved in the biological process described with: mRNA splicing, via spliceosome; mRNA splice site selection.
  
 
 0.984
Prp40
LD24714p; RNA binding. It is involved in the biological process described with: mRNA cis splicing, via spliceosome; mRNA splicing, via spliceosome.
   
 0.972
CG3198
RH42690p; mRNA binding. It is involved in the biological process described with: mRNA splice site selection; mRNA splicing, via spliceosome; positive regulation of gene expression.
   
 0.971
SmB
Small ribonucleoprotein particle protein SmB (SmB) encodes an RNA binding protein that forms a heterodimeric sub-complex with the product of SmD3. They function as part of the heteroheptameric ring complex Sm core, which is involved in the formation of spliceosomal small nuclear RNPs (U1, U2, U4 and U5), which together catalyze pre-mRNA splicing; Belongs to the snRNP SmB/SmN family.

Sf3b1
Splicing factor 3b subunit 1, isoform A; RNA binding; mRNA binding. It is involved in the biological process described with: spliceosomal complex assembly; mRNA splicing, via spliceosome.
   
 0.959
CG4119
BcDNA.LD23634; mRNA binding. It is involved in the biological process described with: regulation of alternative mRNA splicing, via spliceosome; mRNA splicing, via spliceosome.
   
 
 0.958
U2A
Probable U2 small nuclear ribonucleoprotein A; Involved in pre-mRNA splicing as component of the spliceosome (By similarity). Associated with sn-RNP U2, where it contributes to the binding of stem loop IV of U2 snRNA (By similarity). In the germ line, has a role in oogenesis, by regulating spermatogenesis and nurse cell nuclei chromatin decondensation and dispersal, probably by regulating the splicing of proteins necessary for germline differentiation such as the meiotic protein mei-P26. Belongs to the U2 small nuclear ribonucleoprotein A family.
