RABGGTA protein (Homo sapiens) - STRING network view

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 nodes:
protein of unknown 3D structure

large nodes:
some 3D structure is known or predicted

Node Color

colored nodes:
query proteins and first shell of interactors

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

from curated databases

experimentally determined

Predicted Interactions

gene neighborhood

gene fusions

gene co-occurrence

Others

textmining

co-expression

protein homology
