The structure of molecular & cellularThe structure of molecular & cellular networksnetworks
 

Summary: The structure of molecular & cellularThe structure of molecular & cellular
networksnetworks
To be able to construct and analyze a cellular network, we need
to clearly define what we identify as a node and what we
represent with an edge.
The nodes and edges have to be at least similar to each other,
e.g. represent the same type of cellular component (protein,
chemical) or the same type of interaction (mass transfer,
regulation).
We can, and often need to, define different types of nodes and
edges.
Life at the cellular level
ˇ Cellular functions rely on the
coordinated action of interacting
components.
ˇ Proteins
­ provide structure to cells and tissues
­ work as molecular motors
­ sense chemicals in the environment
­ drive chemical reactions
