Interaction networksPrediction, data integration and text mining
the cell cycle
essential process
grow and divide
one cell
two cells
four phases
G1 phase
growth
S phase
DNA replication
G2 phase
growth
M phase
cell division
regulation
gene expression
phosphorylation
targeted degradation
protein interactions

very flexible
lose the STRING interface
payload mechanism
show external data
nodes
edges
