"ZRSR1" - U2 small nuclear ribonucleoprotein auxiliary factor 35 kDa subunit-related protein 1 in Homo sapiens
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:
some 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 each other.
Known Interactions
from curated databases
experimentally determined
Predicted Interactions
gene neighborhood
gene fusions
gene co-occurrence
Others
textmining
co-expression
protein homology

ZRSR1U2 small nuclear ribonucleoprotein auxiliary factor 35 kDa subunit-related protein 1; Zinc finger (CCCH type), RNA-binding motif and serine/arginine rich 1 (479 aa)    
Predicted Functional Partners:
U2AF2
Splicing factor U2AF 65 kDa subunit; Necessary for the splicing of pre-mRNA. By recruiting PRPF19 and the PRP19C/Prp19 complex/NTC/Nineteen complex to the RNA polymerase II C-terminal domain (CTD), and thereby pre-mRNA, may couple transcription to splicing. Induces cardiac troponin-T (TNNT2) pre-mRNA exon inclusion in muscle. Regulates the TNNT2 exon 5 inclusion through competition with MBNL1. Binds preferentially to a single-stranded structure within the polypyrimidine tract of TNNT2 intron 4 during spliceosome assembly. Required for the export of mRNA out of the nucleus, even if the [...] (475 aa)

ZRSR2
U2 small nuclear ribonucleoprotein auxiliary factor 35 kDa subunit-related protein 2; Pre-mRNA-binding protein required for splicing of both U2- and U12-type introns. Selectively interacts with the 3’-splice site of U2- and U12-type pre-mRNAs and promotes different steps in U2 and U12 intron splicing. Recruited to U12 pre-mRNAs in an ATP- dependent manner and is required for assembly of the prespliceosome, a precursor to other spliceosomal complexes. For U2-type introns, it is selectively and specifically required for the second step of splicing (482 aa)

NAP1L5
Nucleosome assembly protein 1 like 5 (182 aa)
     
 
  0.740
RBM17
Splicing factor 45; Splice factor that binds to the single-stranded 3’AG at the exon/intron border and promotes its utilization in the second catalytic step. Involved in the regulation of alternative splicing and the utilization of cryptic splice sites. Promotes the utilization of a cryptic splice site created by the beta-110 mutation in the HBB gene. The resulting frameshift leads to sickle cell anemia; G-patch domain containing (401 aa)
     
 
  0.702
SNRPN
Small nuclear ribonucleoprotein-associated protein N; May be involved in tissue-specific alternative RNA processing events; Sm spliceosomal proteins (240 aa)
     
   
  0.682
COMMD1
COMM domain-containing protein 1; Proposed scaffold protein that is implicated in diverse physiological processes and whose function may be in part linked to its ability to regulate ubiquitination of specific cellular proteins. Can modulate activity of cullin-RING E3 ubiquitin ligase (CRL) complexes by displacing CAND1; in vitro promotes CRL E3 activity and dissociates CAND1 from CUL1 and CUL2. Promotes ubiquitination of NF-kappa-B subunit RELA and its subsequent proteasomal degradation. Down-regulates NF-kappa-B activity. Involved in the regulation of membrane expression and ubiquitin [...] (190 aa)
           
  0.668
PPP1R26
Protein phosphatase 1 regulatory subunit 26; Inhibits phosphatase activity of protein phosphatase 1 (PP1) complexes. May positively regulate cell proliferation (1209 aa)
           
  0.668
U2AF1L4
Splicing factor U2AF 35 kDa subunit-like protein; U2 small nuclear RNA auxiliary factor 1 like 4; RNA binding motif containing (202 aa)
         
0.655
U2AF35
Splicing factor U2AF 35 kDa subunit; Plays a critical role in both constitutive and enhancer- dependent splicing by mediating protein-protein interactions and protein-RNA interactions required for accurate 3’-splice site selection. Recruits U2 snRNP to the branch point. Directly mediates interactions between U2AF2 and proteins bound to the enhancers and thus may function as a bridge between U2AF2 and the enhancer complex to recruit it to the adjacent intron; RNA binding motif containing (240 aa)

U2AFBP
U2 small nuclear RNA auxiliary factor 1; Plays a critical role in both constitutive and enhancer- dependent splicing by mediating protein-protein interactions and protein-RNA interactions required for accurate 3’-splice site selection. Recruits U2 snRNP to the branch point. Directly mediates interactions between U2AF2 and proteins bound to the enhancers and thus may function as a bridge between U2AF2 and the enhancer complex to recruit it to the adjacent intron; RNA binding motif containing (240 aa)
