"ERAP2" - endoplasmic reticulum aminopeptidase 2 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 Size
small protein node
small nodes:
protein of unknown 3D structure
large protein node
large nodes:
some 3D structure is known or predicted
Node Color
colored protein node
colored nodes:
query proteins and first shell of interactors
non-colored protein node
white nodes:
second shell of interactors
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
database edge
from curated databases
experiment edge
experimentally determined
Predicted Interactions
neighborhood edge
gene neighborhood
fusion edge
gene fusions
cooccurrence edge
gene co-occurrence
Others
textmining edge
textmining
coexpression edge
co-expression
homology edge
protein homology

Score
ERAP2endoplasmic reticulum aminopeptidase 2; Aminopeptidase that plays a central role in peptide trimming, a step required for the generation of most HLA class I- binding peptides. Peptide trimming is essential to customize longer precursor peptides to fit them to the correct length required for presentation on MHC class I molecules. Preferentially hydrolyzes the basic residues Arg and Lys (960 aa)    
Predicted Functional Partners:
PDIA3
protein disulfide isomerase family A, member 3 (505 aa)
        score_image score_image score_image   0.926
HLA-B
major histocompatibility complex, class I, B; Involved in the presentation of foreign antigens to the immune system (By similarity) (362 aa)
          score_image score_image   0.925
CALR
calreticulin; Calcium-binding chaperone that promotes folding, oligomeric assembly and quality control in the endoplasmic reticulum (ER) via the calreticulin/calnexin cycle. This lectin interacts transiently with almost all of the monoglucosylated glycoproteins that are synthesized in the ER. Interacts with the DNA-binding domain of NR3C1 and mediates its nuclear export. Involved in maternal gene expression regulation. May participate in oocyte maturation via the regulation of calcium homeostasis (By similarity) (417 aa)
          score_image score_image   0.922
HLA-A
major histocompatibility complex, class I, A; Involved in the presentation of foreign antigens to the immune system (By similarity) (365 aa)
          score_image score_image   0.917
HLA-C
major histocompatibility complex, class I, C; Involved in the presentation of foreign antigens to the immune system (By similarity) (366 aa)
          score_image score_image   0.912
B2M
beta-2-microglobulin; Component of the class I major histocompatibility complex (MHC). Involved in the presentation of peptide antigens to the immune system (By similarity) (119 aa)
          score_image score_image   0.907
TPP2
tripeptidyl peptidase II; Component of the proteolytic cascade acting downstream of the 26S proteasome in the ubiquitin-proteasome pathway. May be able to complement the 26S proteasome function to some extent under conditions in which the latter is inhibited (By similarity) (1249 aa)

TRAT1
T cell receptor associated transmembrane adaptor 1; Stabilizes the TCR (T-cell antigen receptor)/CD3 complex at the surface of T-cells (186 aa)
            score_image   0.741
CAST
calpastatin; Specific inhibition of calpain (calcium-dependent cysteine protease). Plays a key role in postmortem tenderization of meat and have been proposed to be involved in muscle protein degradation in living tissue (750 aa)
            score_image   0.682
LAP3
leucine aminopeptidase 3; Presumably involved in the processing and regular turnover of intracellular proteins. Catalyzes the removal of unsubstituted N-terminal amino acids from various peptides (519 aa)
