Immunohistochemistry of those EGFRs that are statistically associated proteins. Proteins with statistically significant associations are represented with their statistical values (Pearson correlation and p-value associated) and by immunohistochemistry staining.

APID Network. Proteins displayed by APID without filters. Proteins are more or less close to EGFR according to their cluster coefficient.

The table shows 21 proteins with greater evidence for EIP (EGFR interacting proteins). The cluster coefficient, a graph parameter that indicates the degree of inter-connection of the group of proteins directly interact to a query protein, in our case, EGFR. A cluster coefficient value close to zero indicates that the protein pair is very close, a value away from zero shows that the protein pair is farthest.

EGFR scores for the interactors obtained by STRING

The table shows all associations in STRING provided with a probabilistic confidence score for EIP and between proteins belongs to this EGFR interactome network. Each node represents a protein which by edges may be interacting with any other. Each score represents a rough estimate of how likely a given association describes a functional linkage between two proteins that is at least as specific as that between an average pair of proteins annotated on the same ‘map’ or ‘pathway’ in KEGG. *Proteins showed by STRING and APID as EIP.
