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

jamm1Metalloprotease JAMM1, desampylating; Metalloprotease that displays desampylase (DSAMP) activity, cleaving ubiquitin-like small archaeal modifier proteins (SAMP1, SAMP2 and SAMP3) from protein conjugates (isopeptide- and linear-linked). Thus, likely regulates sampylation and the pools of 'free' SAMP available for protein modification. Functions as a specific and not a general protease since it is unable to hydrolyze a variety of unmodified proteins otherwise hydrolyzed by proteinase K. (139 aa)    
Predicted Functional Partners:
ubaA
SAMP-activating enzyme E1; Likely activates multiple ubiquitin-like SAMPs for protein conjugation as well as for sulfur transfer, via ATP-dependent adenylation at their C-terminus. In fact, it is required for the formation of all three SAMP1-, SAMP2- and SAMP3-protein conjugates, and for molybdenum cofactor (MoCo) biosynthesis and thiolation of tRNAs.

glpK
Glycerol kinase; Key enzyme in the regulation of glycerol uptake and metabolism. Catalyzes the phosphorylation of glycerol to yield sn- glycerol 3-phosphate. It also catalyzes the phosphorylation of dihydroxyacetone (DHA). Involved, together with the DHA kinase DhaKLM, in the metabolism of DHA.

samp2
Ubiquitin-like modifier protein SAMP2; Functions as a protein modifier covalently attached to lysine residues of substrate proteins, as well as a sulfur carrier in tRNA thiolation. The protein modification process is termed sampylation and involves the formation of an isopeptide bond between the SAMP2 C- terminal glycine carboxylate and the epsilon-amino group of lysine residues on target proteins. Is able to form polymeric chains with itself at Lys-58, similar to ubiquitin and other ubiquitin-like proteins. May serve as a proteolytic signal in the cell to target proteins for degradati [...]

panA
Proteasome-activating nucleotidase; ATPase which is responsible for recognizing, binding, unfolding and translocation of substrate proteins into the archaeal 20S proteasome core particle. Is essential for opening the gate of the 20S proteasome via an interaction with its C-terminus, thereby allowing substrate entry and access to the site of proteolysis. Thus, the C- terminus of the proteasomal ATPase functions like a 'key in a lock' to induce gate opening and therefore regulate proteolysis. Unfolding activity requires energy from ATP hydrolysis, whereas ATP binding alone promotes ATPas [...]

rpl40e
50S ribosomal protein L40e; Belongs to the eukaryotic ribosomal protein eL40 family.

rps19
30S ribosomal protein S19; Protein S19 forms a complex with S13 that binds strongly to the 16S ribosomal RNA.

panB
Proteasome-activating nucleotidase; ATPase which is responsible for recognizing, binding, unfolding and translocation of substrate proteins into the archaeal 20S proteasome core particle. Is essential for opening the gate of the 20S proteasome via an interaction with its C-terminus, thereby allowing substrate entry and access to the site of proteolysis. Thus, the C- termini of the proteasomal ATPase function like a 'key in a lock' to induce gate opening and therefore regulate proteolysis. Unfolding activity requires energy from ATP hydrolysis, whereas ATP binding alone promotes ATPase- [...]

Ubiquitin-like modifier protein SAMP1; Functions as a protein modifier covalently attached to lysine residues of substrate proteins, as well as a sulfur carrier in molybdenum cofactor (MoCo) biosynthesis. The protein modification process is termed sampylation and involves the formation of an isopeptide bond between the SAMP1 C-terminal glycine carboxylate and the epsilon-amino group of lysine residues on target proteins. May serve as a proteolytic signal in the cell to target proteins for degradation by proteasomes.

rps3
30S ribosomal protein S3; Binds the lower part of the 30S subunit head. Belongs to the universal ribosomal protein uS3 family.

tif2a
Translation initiation factor aIF-2 alpha subunit; eIF-2 functions in the early steps of protein synthesis by forming a ternary complex with GTP and initiator tRNA. Belongs to the eIF-2-alpha family.
