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

Ate1Arginyl-tRNA--protein transferase 1; Involved in the post-translational conjugation of arginine to the N-terminal aspartate or glutamate of a protein. This arginylation is required for degradation of the protein via the ubiquitin pathway. Does not arginylate cysteine residues (By similarity). (485 aa)    
Predicted Functional Partners:
Ubr1
E3 ubiquitin-protein ligase UBR1; E3 ubiquitin-protein ligase which is a component of the N-end rule pathway. Recognizes and binds to proteins bearing specific N- terminal residues that are destabilizing according to the N-end rule, leading to their ubiquitination and subsequent degradation. Belongs to the UBR1 family.

Ntan1
protein-N-terminal asparagine amidohydrolase activity. It is involved in the biological process described with: positive regulation of DNA endoreduplication; ubiquitin-dependent protein catabolic process via the N-end rule pathway; negative regulation of glial cell proliferation; ubiquitin-dependent protein catabolic process.

tun
Protein N-terminal glutamine amidohydrolase; Mediates the side-chain deamidation of N-terminal glutamine residues to glutamate, an important step in N-end rule pathway of protein degradation. Conversion of the resulting N-terminal glutamine to glutamate renders the protein susceptible to arginylation, polyubiquitination and degradation as specified by the N-end rule. Does not act on substrates with internal or C-terminal glutamine and does not act on non-glutamine residues in any position. Belongs to the NTAQ1 family.

Naa80
N-alpha-acetyltransferase 80; N-alpha-acetyltransferase that acetylates the amino terminal acidic residue of proteins devoid of initiator methionine. Preferentially acts on proteins starting with Asp- Asp-Asp and Glu-Glu-Glu sequences. In vitro, shows high activity towards N-terminal sequences starting with Met-Asp-Glu- Leu, Met-Glu-Glu-Glu and Met-Asp-Asp-Asp.

eIF1A
Eukaryotic translation initiation factor 1A (eIF1A) encodes a protein required for mRNA translation. It is involved in 43S pre-initiation complex assembly, ensuring correct AUG start codon selection, and its dissociation from the 40S ribosome subunit is considered crucial for start codon recognition.

Ubr3
E3 ubiquitin-protein ligase Ubr3; E3 ubiquitin-protein ligase which is a component of the N-end rule pathway. Recognizes and binds to proteins bearing specific N-terminal residues, leading to their ubiquitination and subsequent degradation. Binds to the E3 ubiquitin-protein ligase Diap1 and enhances its ubiquitination and anti-apoptotic functions. Essential during trichome development for the ubiquitination of the N-terminus of ovo isoform B (svb), converting it from a transcriptional inhibitor to an activator. Positively regulates a hh-signaling pathway which functions in photorecepto [...]

poe
Protein purity of essence; Has a role in growth of the perineurial glial layer of the larval peripheral nerve. May have a role in male fertility and eye development or function. Involved in the negative regulation of the Ras/MAPK signaling pathway in the wing by acting with the E2 enzyme Unc6 and the putative E3 ligases Kcmf1 and Ufd4 to mediate the ubiquitination and proteasomal degradation of rl/MAPK.

CG42450
Uncharacterized protein, isoform B; It is involved in the biological process described with: intracellular signal transduction; G protein-coupled receptor signaling pathway.

RIC-3
RIC3 acetylcholine receptor chaperone (RIC-3) encodes a protein that assists with nicotinic acetylcholine receptor protein folding.
