"GCN1L1" - eIF-2-alpha kinase activator GCN1 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

GCN1L1eIF-2-alpha kinase activator GCN1; Acts as a positive activator of the EIF2AK4/GCN2 protein kinase activity in response to amino acid starvation. Forms a complex with EIF2AK4/GCN2 on translating ribosomes; during this process, GCN1 seems to act as a chaperone to facilitate delivery of uncharged tRNAs that enter the A site of ribosomes to the tRNA- binding domain of EIF2AK4/GCN2, and hence stimulating EIF2AK4/GCN2 kinase activity. Participates in the repression of global protein synthesis and in gene-specific mRNA translation activation, such as the transcriptional activator ATF4, by pr [...] (2671 aa)    
Predicted Functional Partners:
EIF2AK4
eIF-2-alpha kinase GCN2; Metabolic-stress sensing protein kinase that phosphorylates the alpha subunit of eukaryotic translation initiation factor 2 (eIF-2-alpha/EIF2S1) on ’Ser-52’ in response to low amino acid availability. Plays a role as an activator of the integrated stress response (ISR) required for adapatation to amino acid starvation. Converts phosphorylated eIF- 2-alpha/EIF2S1 either to a competitive inhibitor of the translation initiation factor eIF-2B, leading to a global protein synthesis repression, and thus to a reduced overall utilization of amino acids, or to a transla [...] (1649 aa)
     
 
  0.984
CDC5L
Cell division cycle 5-like protein; DNA-binding protein involved in cell cycle control. May act as a transcription activator. Component of the PRP19-CDC5L complex that forms an integral part of the spliceosome and is required for activating pre-mRNA splicing. The PRP19-CDC5L complex may also play a role in the response to DNA damage (DDR); Myb/SANT domain containing (802 aa)
     
      0.981
HARS
Histidine--tRNA ligase, cytoplasmic; Cytoplasmic histidine--tRNA ligase (Probable). Plays a role in axon guidance; Aminoacyl tRNA synthetases, Class II (509 aa)
     
 
  0.960
ABCF3
ATP-binding cassette sub-family F member 3; Displays an antiviral effect against flaviviruses such as west Nile virus (WNV) in the presence of OAS1B; ATP binding cassette subfamily F (709 aa)
     
 
  0.916
DRG2
Developmentally-regulated GTP-binding protein 2; May play a role in cell proliferation, differentiation and death; Belongs to the TRAFAC class OBG-HflX-like GTPase superfamily. OBG GTPase family (364 aa)
     
 
  0.901
FAF2
FAS-associated factor 2; Plays an important role in endoplasmic reticulum- associated degradation (ERAD) that mediates ubiquitin-dependent degradation of misfolded endoplasmic reticulum proteins. Involved in inhibition of lipid droplet degradation by binding to phospholipase PNPL2 and inhibiting its activity by promoting dissociation of PNPL2 from its endogenous activator, ABHD5 which inhibits the rate of triacylglycerol hydrolysis; UBX domain containing (445 aa)
     
      0.863
UBAC2
Ubiquitin-associated domain-containing protein 2; Restricts trafficking of FAF2 from the endoplasmic reticulum to lipid droplets; Rhomboid family (344 aa)
       
      0.860
RWDD1
RWD domain-containing protein 1; Protects DRG2 from proteolytic degradation; Belongs to the RWDD1/GIR2 family (243 aa)
     
 
  0.850
PDCD11
Protein RRP5 homolog; Essential for the generation of mature 18S rRNA, specifically necessary for cleavages at sites A0, 1 and 2 of the 47S precursor. Directly interacts with U3 snoRNA; Minor histocompatibility antigens (1871 aa)
     
   
  0.826
CIRH1A
U3 small nucleolar RNA-associated protein 4 homolog; Ribosome biogenesis factor. Involved in nucleolar processing of pre-18S ribosomal RNA. Involved in small subunit (SSU) pre-rRNA processing at sites A’, A0, 1 and 2b. Required for optimal pre-ribosomal RNA transcription by RNA polymerase. May be a transcriptional regulator. Acts as a positive regulator of HIVEP1 which specifically binds to the DNA sequence 5’-GGGACTTTCC-3’ found in enhancer elements of numerous viral promoters such as those of HIV-1, SV40, or CMV (686 aa)
