Summary: The structure of cellular networksThe structure of cellular networks
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 Gene mRNA protein
ˇ Proteins
provide structure to cells and tissues
work as molecular motors
sense chemicals in the environment
drive chemical reactions
regulate gene expression
ˇ Cellular functions rely on the
coordinated action of gene products.
