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

cxr1Uncharacterized RNA-binding protein C23E6.01c. (473 aa)    
Predicted Functional Partners:
usp105
Pre-mRNA-processing factor 39; Function prior to stable branch point recognition by the U1 snRNP particle to facilitate or stabilize the U1 snRNP/5'-splice site interaction. Has a direct role in the assembly or function of a catalytically active spliceosome (By similarity); Belongs to the PRP39 family.
   
 0.936
usp103
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. usp103/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.
   
 0.907
usp107
U1 snRNP-associated protein usp107; Component of the U1 snRNP particle, which recognizes and binds the 5'-splice site of pre-mRNA. Together with other non-snRNP factors, U1 snRNP forms the spliceosomal commitment complex, that targets pre-mRNA to the splicing pathway.
   
 0.904
lea1
U2 small nuclear ribonucleoprotein A; Involved in pre-mRNA splicing. This protein is associated with sn-RNP U2. It helps the A' protein to bind stem loop IV of U2 snRNA (By similarity).
   
 0.903
usp101
U1 small nuclear ribonucleoprotein 70 kDa homolog; Involved in nuclear mRNA splicing (By similarity). Essential for growth.
   
 0.902
luc7
U1 snRNP-associated protein usp106; Component of the U1 snRNP particle, which recognizes and binds the 5'-splice site of pre-mRNA. Together with other non-snRNP factors, U1 snRNP forms the spliceosomal commitment complex, that targets pre-mRNA to the splicing pathway.
    
 0.902
smd1
Small nuclear ribonucleoprotein Sm D1; Involved in pre-mRNA splicing. Binds snRNA U1, U2, U4 and U5 which contain a highly conserved structural motif called the Sm binding site (By similarity).
   
 0.897
prp2
Splicing factor U2AF 59 kDa subunit; Necessary for the splicing of pre-mRNA. The SF1-U2AF59-U2AF23 complex has a role in the recognition of the branch site (5'-UACUAAC- 3'), the pyrimidine tract and the 3'-splice site at the 3'-end of introns; Belongs to the splicing factor SR family.
   
 0.897
prp10
U2 snRNP component prp10; Contacts pre-mRNA on both sides of the branch site early in spliceosome assembly; Belongs to the SF3B1 family.
   
 0.897
sme1
Small nuclear ribonucleoprotein E; Involved in pre-mRNA splicing. Binds and is required for the stability of snRNA U1, U2, U4 and U5 which contain a highly conserved structural motif called the Sm binding site. Involved in cap modification (By similarity).
