Lecture #4
How cell cycle is regulated?
Signaling pathway
Different signaling pathways use different mechanisms for signal transduction.
Those mechanisms have different kinds of on/off switches
Competitive inhibitor
EGF pathway regulates cell division, and is mutant in many cancers.
Epidermal Growth Factor (EGF) pathway
Dimerize—dimer
2 common techniques
DNA is negatively charged
WT: 1000kDa, larger
Mutant: <1000kDa, smaller
